Question

5. Each base angle of an isosceles triangle is 15° more than its vertical angle. Find each angle of the triangle
​

Answer 1

Let be consider the angles of isosceles triangle is x , x+15 & x+15
By angle sum property of triangle
X + X+15+X+15=180
3x+30=180
3x=180-30=150
X=150/3=50

Then angles are 50, 65 & 65
