Question

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

u = <8, 7>, v = <9, 7>

Answer 1

Got it!

Answer 2

Oh good job! c:

Answer 3

Actually I need help :( @zepdrix

Answer 4

I'm stuck in a part where I have (121)/ the square root of 145 and the square root of 98

Answer 5

So how are we finding the angle between them? Using this identity?\[\large \cos \theta=\frac{\vec u \cdot \vec v}{|u|\cdot|v|}\]Hopefully I remembered that correctly...
