Question

Find the angle between the given vectors to the nearest tenth of a degree.

u = <-5, 8>, v = <-4, 8>

Answer 1

\(\Large\color{black}{ \displaystyle \theta=\rm{ArcCosine}\left(\frac{\vec{\bf u}\cdot \vec{\bf v}}{\left|\left|\vec{\bf u}\right|\right|\cdot\left|\left|\vec{\bf v}\right|\right|}\right) }\)

Answer 2

where, \(\left|\left|\vec{\bf v}\right|\right|\) demotes "the maginute of vector v"

Answer 3

And, I said the exact same thing in your previous question.
In any case, I hope that helps.

Answer 4

im very confused
