Question

Each of the two equal angle of an isosceles triangle is twice the third angle. Find the angles of the triangle.

Answer 1

the two equal angles are 72 and the third angle is 36

Answer 2

Let the third angle be x and one of the equal angles be 2x
x+2x+2x=180(Angle sum property)
5x=180
x=36
Therefore the three angles are 36, 72 and 72.
