Question

In an isosceles triangle ,the base angles are equal and the vertex angle is thrice of
base angle.Find the measure of each angle?

Answer 1

Answer:

let base angle = x

vertex angle = 3x

by angle sum property of triangle

x + x + 3x = 180°

5x = 180

x = 180/5

x = 36

thus all angles are 36, 36 , 108
