we could use the law of cosines to find side c, and then the law of sines to find angle A

i The only angle you are given is C, so use c^2 = a^2 + b^2  2abcosC...now substitute

This is a 2 step problem. find side c using \[ c^2 = a^2 + b^2  2\ a\ b \cos(C) \] after you find c, you can use the Law of Sines \[ \frac{\sin A}{a}= \frac{\sin C}{c} \]
