The law of sines reflects that any triangle with sides a, b, and c and angles opposite those sides A, B and C have the following relationship sin(A)/a = sin(B)/b = sinC/c therefore a = sin(A) *b /sin(B) From this you can compute the side of a triangle if you now the angle opposite and another angle of the triangle and its side opposite
