What do you mean?

I think it is mainly using cosine, sutract sum of angles found from 180, then sine for the rest of the triangle to be solved.  but i do not know how to determine if there are two triangles, one triangle, or no triangles.  if there are two triangles i am a bit confused on how to find that.
