## anonymous one year ago 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?

1. dumbcow

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

2. anonymous

no? @dumbcow

3. dumbcow

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

4. dumbcow

do you know how to find dot product and magnitude?

5. anonymous

not really. @dumbcow
