What is the angle between v= (-7,8) and w =(5,3)

Answer 1

There;s another way to find it too!

Answer 2

But that's not cosine thing.

Answer 3

Cos Law maybe?

Answer 4

Hey, i just met you
And this is the problem
I dont know cos rule,
so tan rule maybe! :D

Answer 5

that'll work. cos law wouldn't work without that thrid say anyways (you can find it, but it takes a bit more time to do Cos Law)

Answer 6

We can use the distance for that side.

Answer 7

o, graphin it out would help too

Answer 8

99.93?

Answer 9

havent doen the math myself. if others would like, maybe show yur work
