This uses the fact that if two angles in a triangle are congruent, then two sides in the triangle are congruent. So we have an isosceles triangle (two equal sides and a base.)

There are two ways to make this triangle isosceles. Side lengths {50, 50, 30} or {30, 30, 50}. In the second case, the perimeter will be smaller. P = 30 + 30 + 50 = 110 is smallest possible perimeter.
