To 'solve' a triangle means to find all the missing values for the sides and angles. In this case, the lengths of 2 sides and the size of 1 angle are given, we have to find the size of the 3 rd side and the other 2 angles.

color(green)(hat C = 70, hat B = 60, b = 24.87

Explanation:

enter image source here

sin C = (c sin A) / a = (27 sin 50) / 22 = 0.9401

hat C = sin ^-1 0.9401 = 70^@

hat B = 180 - 50 - 70 = 60^@

b = (a * sin B) / sin A = (22 * sin 60) / sin 50 = 24.87
