    What do you mean by "solve"? You already have provided the three side lengths.

    The three angles A, B, and C can be computed by using the law of cosines.

    c^2 = a^2 + b^2 - 2 a *b cos C

    cos C = (a^2 + b^2 - c^2)/(2 a b)
    and two other rearrangements of the same formula for A and B
