Let the vertical angle be a.
So, each of the base angles is 2a.
All that we need to know now is that the sum of the angles is 180 degrees.
a + 2a + 2a = 5a = 180
a = 36 degrees
So, the angles are 36,72,72
an isosceles triangle is such that each of the base angles is twice the vertical angle. Find the angles of the triangle
