Question #3690

How do you find a second side of a triangle with using one side and two angles ?

Expert's answer

From Sin Rule we have:

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, c - the sides of& the triangle,& A, B, C - are the angles opposite to the corresponding sides (a, b, c respectively)

a/sin(A) = b/sin(B) = c/sin(C)

where a, b, c - the sides of& the triangle,& A, B, C - are the angles opposite to the corresponding sides (a, b, c respectively)
