A + 2(A + 15) = 180
A + 2A + 30 = 180
3A = 150
A = 50 degrees

each base angle of an isosceles triangle is 15 more than the vertex angle. What is the measure of the vertex angle
-----
vertex angle:: x degrees
base angle: x+15
-----
Equation:
x + 2(x+15) = 180
x + 2x + 30 = 180
3x = 150
x = 50 degrees (Measure of the vertex angle.
