In △ ABC, the angles a, B and C are opposite to three sides a, B and C respectively. It is known that a = 5, B = 2 and B = 120 ° to solve the triangle
Because a = 5, B = 2, B = 120 degrees, so a > B = 120 degrees, so a + B > 240 degrees, which is contradictory to a + B + C = 180 degrees, so this triangle has no solution
