I will give a medal, and a fan, but I have to go, so it may take like an hour, and I'll eventually get what you guys post :P

All the angles?$$c^2 = a^2 + b^2 - 2ab\cos(\gamma)$$$$b^2 = a^2 + c^2 - 2ac \cos(\beta)$$$$a^2 = b^2 + c^2 - 2bc\cos(\alpha)$$Use the values of a,b, and c

I would draw the triangle,  label all the sides.

then label the angle you want to solve

then use the formula.
