Question

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

u = <-5, -4>, v = <-4, -3>

i got -9.1 am i right?

Answer 1

did you use
\[\cos \theta = \frac{u*v}{|u| |v|}\]

Answer 2

no? @dumbcow

Answer 3

ok well that is the equation you need to use for finding angle between vectors

Answer 4

do you know how to find dot product and magnitude?

Answer 5

not really. @dumbcow
