What is the measurement of the vertex angle of an isosceles triangle is the measure of one of its base angle is 42?

The vertex angle of an isosceles triangle is equal to the measure of each of its base angles. Therefore, if one of the base angles measures 42 degrees, then the vertex angle also measures 42 degrees.
