In an isosceles triangle, there are three angles. Two base angles that are congruent, x∘, and a vertex angle, y∘. From the exercise, we know that the vertex angle is 30∘ Let's add this information to the yellow triangle.
According to the Triangle Sum Theorem, the sum of the measures of the interior angles of a triangle is 180∘. Therefore, we can write the following equation
