the sin rule says sin c/sin C = sin b/sin B = sin a/sin A. Since I don't have C or c, i don't see how I can use it. the cosine rule says cos c = cos a cos b + sin a sin b sin C. Since I don't have c or C, I don't see how to use it either. :(

Im trying to use spherical trig to solve a problem In the standard method to compute the angles, I already have only the following four angles A, a, B, b but from these, how can I compute either C, or c? Thanks
