those are degrees
cosine formula is a good option
Ah. Law of sines: \[\frac{\sin(a)}{A}=\frac{\sin(b)}{b}\] Law of cosines is \[c^2 = a^2+b^2 - 2ab\cos(C)\] So what are you given that can be used here?

cannot be solved
Sorry the law of sines should have been: \[\frac{\sin(A)}{a}=\frac{\sin(B)}{b}\]
the angles
oh and side b
Yes it can. You have 1 side and three angles
so law of sines?
And i flipped all my capitol letters with the convention. Yes, Multiple uses of Law of sines would solve the triangle. You would have to do a 180-a-b to get angle c though...
