    Solving the triangle means you have to calculate all 3 vertices and angles.

    Since you know a, b and C, you need to calculate c, A and B

    To calculate c, you need Law of Cosine: c^2 = a^2 + b^2 - 2abcosC

    Once you get c, you can apply Law of Sine: a/sinA = b/sinB = c/sinC, then you will get sinA and sinB, which you can do the inverse function arcsin to get A and B
