Question

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

u = <6, -1>, v = <7, -4>

Answer 1

u.v = |u| |v| cos A

where A is the angle to be found, u.v is the scalar product of the 2 vectors and |u|
and |v| are the magnitudes of u and v

Answer 2

thank you, i think i figured it out
