Find the exact value of each expression. Do not use a calculator. $\sin 30^{\circ} \cdot \tan 60^{\circ}$

Here we have to calculate the value of the function given by sign off. Minus off 20 Degree. A born off course off. Three year degree. Bless off Ben Gentles. 200 bigly. No, we know that sign off. Minus data is equals to minus off. Science hitter goes off. Do pipe Lassiter is equals to ghostwriter and engine both When a people is Tita, is it closed toe then gente as when it is equals two pi we can right here. 10 years off. 5% bicycles to tension, Tita. So we can right here. Sign off. Minus 20 degree equals two minus off. Signed 20 degree upon off Goes off 3 60 plus off 20 degree Bless off tangent off one it day Degree plus off corn DDT. So this converted in AZ minus off. Signed 20 degree A bone off course 20 degree Bless off pensioned off. 20 degree. No sign of by course scientific data. A born off course tutor Is it closed toe tangent off. So we will have minus off Ben Gente bless off penchant off 20 degree So these votes will be cancelled out and we have sign off Minus 20 degree by course, off 3 80 degree plus off tangent off 200 degree is equals to zero

Given the equation system of linear equation two x minus three. Y plus six. Said minus five T equal to three. Why -4? White. My minus full set plus The equal to one. Four x minus five Y plus eight said minus 90 equal to keep. So using these coefficients we can write our metrics. We can form a metrics and 31 keys metrics. See Cool. Yeah. Sorry baby. Then augmented matrix C. Is the augment metrics A B raise the matrix of coefficients. And these the metrics of artists values. Then C. Is equal to. First question considers substitution to 36 -53 please. The artistic value Then second question we get 01 -4 11 30 Question 4 -5. 8 -9. Kate, Saudi. Then doing the raw operations, three changes to 3 -201. During this operation we get metrics to minus 36 minus 5301 minus 411. R one and r two have no changes in our three becomes 01 minus food one K -6. Now another row operation we're doing three changes to three minus R. Two. Then we get the metrics to -36 -5. 3 And 01 -411 Are not the same. The battery becomes zero zero 00 and K -7. This is the augmented matrix A. B. This is metrics say. And this is metrics be and this is seat. We knew that first. If there is no solution there is no solution. Yeah if rang of a not equal to rank of augmented matrix. Let it sprang off. See here Randolph is two. Okay. And Rangelov, C is three. So these two are different. Okay. Provided the condition came in a seven not equal to zero. If came in a seven equal to zero, what will become the rank of the metric? See become too then rank a fee equal to wrangle. See therefore does uh no solution condition changes. Therefore K minus seven not equal to zero. Which symbolize K not equal to seven. If ken article two servant, there is no solutions. Okay, no infinite solution. Uh huh. Infinite solution. Of course when Rango fee equal to rank of C which is less than four terry. Clearly we have Randolph is two and rank of C equal to same to becomes when K minus seven equal to zero. That is when K equal to seven. So when K equal to seven, we get infinite number of solutions. For the current options are A and big thank you.

The question is 10 of 720°- schools to 70° minus sign 1 50 degree in two goals. 1 20 degree. Okay So let's check. 7 20°. That is That Campbell witness? 10 of two into 3 60 degree. That is 7:20 -270 can be written as three into 90. We are approximately we are changing this value so on the basis of 91 83 60. Okay that values so this is three and u 90 degree minus sign 1 50 can be written us uh when it is near to 1 50 so we can to sign off 1 80 degree minus 30 degree In do 1 20 can be rudeness Uh because of 1 18 -60°. Okay then the values this is zero of course 90. So this will be zero then this is sign 30° And this will be -160. So values is 0 0- sign 30 Nikki Into minus goes 60° at this -1 x two into -1 x two. That is one x 4. No second question. It is given a sign 600° In the coast. 3 30° Bliss. Because 1 20 degree inducing 1 50 degree. Okay. Say mr Bill changing disasters. Sign off 3 60 plus 2 40 degree. That's 600. In the course of this can be redressed 360° -30° plus. Course 1 20. It is because 90 plus 30°. Yeah, thank you In to sign 150, that is 180 30 degrees. A moment 50 degree. We use 1 80 minus and if the angle is below 1 50 we can use 90 plus. Okay like boys. Now the values it will be signed to 40° In due course 30° minus sign 30 and you say 13. Mhm. You see two -3 x two in new Route three x 2 -1 x two into 1 x two. This is minus three by two minus one by two. That is minus four by two. That is minus four x 4. Okay sorry to it's full 200- four. Okay That is -1. Okay, Now the 3rd question there's a question. Cool. Square 1 18 minus go Squire 36 degree minus go square 54 degrees plus course quail. Sound to degree. Yeah. Okay. This can be a witness of course square 18. Yeah. Mhm. My school square nine g -54. That is 36- of course where 54 mhm. Plus go square 90 -18°. Okay, this is sine square 54 And this will be called Square 18. So that is school square sorry uh square 18 minus sine square 54 degree. Well that's Square 54 degree Plus Sine Square 18 Degree. Okay. Weekend arrange the terms and can right cause square 18 degree plus Sine square 18 degree. I just put a bracket order and minus soft Sign Square 54 plus Course Square 54. We know that science square expert schools could exist 1 1 -1. That is zero. Okay whatever may be the angle it's zero. Yeah now the food question minus stan Tito and do we'll see the tongue. I do minus sick Tito divided by minus tante to into six creditor in your court. Yeah. Okay. Mhm. We know that Peter in the co 60 days of sick data. So that is mm city to indu mine city to divided by minus stand peter Indu Six square victory in due course data can be written as one x 10 cake down. This is minus okay. Mhm. So we help since there isn't mine is over here we can write minus 60 tend to my inner city to buy my understanding to into six credit and do one by 20 to 20. Got canceled. Sick stater Six credit and this minus minus called candles we have at the sequel to -1. Okay Just got this is -6 data into -6 data. So six core data. This written us one by tan Theta the standard that Dante called canceled and minus six core data. six creditor by -6 creditor is -1 that stuff. And so now this is the question that is Court 11 by by 20 into court 13 Bye Bye. 20 into court 15 by by 20 In the court 17 by by 20 Into Court 19 by by 20. Okay we need to find the answer of this. This can be written us the sequel to court off Bye bye two plus by by 20 11 bite. Uh, Friendly can be written us by by two plus by by 20. If we take 20 by Plus you pay by 40 just 17 baby 40 that is took him Okay. It can be written. Okay. So the answer we can write a task court Bye bye two plus by by 20 in new court by by two plus the third Three pay by 20 we can write like that. Okay. The next term can be written as caught off. Bye bye to plus five by by 20 that the same as one by folk. So we can write it us baby for indoor called P -3 pay by 20 into court by- by by 20. Yeah. So you think if technocratic guidance this weekend right like this and it's so become caught off by by two plus three days minus 10 theater. So we got minus tank pay by 20 into my inner span three by by 20 into my understand paid by food then caught up. I minus three pay by 20 that will become minus court three pay by 20 in your next time become minus court. Bye Bye. 20. Okay. And the value of this is equal to minus what? Okay. Yeah. Yeah. So that's it

Here we are given me sign off. 70 degree, A bone goes off minus or 4 30 degree Bless. Off pendant off, minus sound DDT? No, we know that. Go So attendant off Minnesota is equals to minus off 10 gente Also we know that goes off to buy blasted er is equals to Costinha Also tended off Minus data is it goes through my understanding. Thida course off minus data is a cause to go Stater and scientist Abiko Sita is it? Gordo? Benyon Tudo, We're going to use all these identities or formulas. No, this will be Gordo. Sign off. Sound a degree. A blown off goes off my nest. A double vehicle Tow course off data. So this will be equal to call. So 430 degree plus off tangent off minus 30 minus 70 Will be equals two minus off. Penchant 70 degree. Now this will be close to sign off. 70 degree. A blown off goes off 3 60 degree plus off. 90 degree minus off penchant. So be Diggory. This will vehicles to course off. Sign off. Sound a degree. A bone off goes off. Sounded dignity minus off pendant 70 degree. So this can be read iness Ngentle sound did agree minus off Benji Andov sound de degree and this will be equals 20 So we have sign off. 70 degree upon course, off minus off for 30 degree plus often yet off minus under degree is equals to zero.
