explains law of cosine

- Hey man you wanna play some pool?
- Yea sounds like fun
- Im on the 8ball
- only way to win is by trickshot
- hmmm how could i bank this shot ?
- idk man seems kinda hard
- only way to do this is to use the law of cosine
- yea that could be useful
- I have these numbers so I can find the length of c.
- C2=a2+b2-2abcos(C)X2=52+32-2(5)(3)cos(160)X2=34-30cos(160)X2=62.19077862X=8
- I have found the length of C thanks to the law of cosine.
