Find the angle between the vectors. $\mathbf{u}=(-4,3), \quad \mathbf{v}=(0,5), \quad\langle\mathbf{u}, \mathbf{v}\rangle=3 u_{1} v_{1}+u_{2} v_{2}$

Find the angle between the vectors. $\mathbf{u}=(-4,3), \quad \mathbf{v}=(0,5), \quad\langle\mathbf{u}, \mathbf{v}\rangle=3 u_{1} v_{1}+u_{2} v_{2}$



Answers

Two vectors u and v are given. Find the angle (expressed in degrees) between u and v.
$$
\mathbf{u}=\langle 2,-2,-1\rangle, \quad \mathbf{v}=\langle 1,2,2\rangle
$$
