We're trying to find the angle state of between vectors U and V. We can start out by knowing that co sign of data is equal to you dot v over absolute value of you dot Absar value v magnitude. And we can first start by working on what you dot visas. And if we already know you envy, we can just start right away with one that'll Kirby there one dot for plus two o plus negative to negative three and that is four plus zero plus 6 +74 and six would be 10. Next step we have our magnitude of you is equal to root of one squared plus two squared plus negative two squared just going to be able to 48 and nine and Route nine is equal to three. Then we have or absolute value the which is going to be four squared. We can ignore zero plus a negative three squared. Yes, we have 16 and nine, which is route 25. Nice clean numbers here That's equal to five. So now we know that co sign of data is equal to 10/3 times five and then we can know that data is equal to inverse co sign of 10/15 and 10/15 is the same as to over three, and then the inverse co sign of two of her three as a decree would be 48.19 degrees.

Okay, so this problem wants us. Teoh Multiply by Naval by Cor Tick So we have K plus two times 12 cake You'd minus three case Where plus K plus wine. Okay, um, to solve this, I'm just going to district distribute. Over. Addition, I'm seven. Multiply everything by K and then by two. So I have 12 k to the fore, minus three k cubed plus case, Grand plus K. Then I most want everything About two. I'm gonna have 24 k cubed, minus six k squared plus two K plus two. Okay, lets together. I'll have my final polynomial. So I have 12 k to the fore plus 21 K cubes minus five. Case where? Let's three K plus two. Okay, thank you very much.

It was valuable, but iyc agenda I rest three j minus two Gay How can register and you know, 13 months Q And if it'll be we crocheted to I minus tree K. I can understand you choose romanced three and from here you can find the length on a better A by phone Long interpreted the one square best three square plus minus two square Then we get Nico Junior square Root off the 14 something for the be getting Could you square it under two square Best their square vestments three square and event in coach in the square Root on uh, Dean um recording the because I am the angle which Ilija vetters in coaching Ida B over the Lanham that many times their land and be so I dont be we get a culture one times two plus three times There are blessed minus two times with the ministry they running bind a square under 40 in Times Square on a 13 And now on the tom again, Echo Children two plus six They could you ate dividing by the square root on, uh, far too many times it could you one I did. You doesn't mean stand the angle. Tita echoed a course. I inverse off the eight over 182 and then we get a good Jew. Go sign DOESn't equal Jew £53.63 degree.

So solve this equation. Here we are going to multiply both sides by the LCD so we can see that the LCD is equal tow n plus one times and plus seven. So that means we're going to multiply on my side by the LCD. We're also going to multiply the right side by the LCD. Now we end up with and kinds on plus seven on the left side, and the right side is going to be six times and plus one fact distributing that will give us and square plus seven and is equal to six on six. Move everything over in the left side. Now we get unscored plus on minus six is equal to zero, so that can be factored into unplugged three times on minus two. So that gives us and it's equal to make it a three or a sequel. Now we can see that neither of those answers will give us a zero that are denominator. So which means both of them should be good answers you can. We'll go back into the original equation to check. So for friend is equal to negative three. That gives us negative three over negative three plus one is equal to six over, maybe 23%. So the left side is going to be negative. Three over. Thank you, too. And then the right side is going to be, um, six over for it's so this last seven cups positive through, over to, and the right side is also there over to once we simple. So that's good. You know, we check any clothes, too. That'll be to over two plus one, and that's six over to plus up. So this is true. Over three is equal to six overnight, which is true because six overnight simplifies to Children.
