Question

In an isosceles triangle the base angles are equal. The vertex angle is 3 times the base angle.
Find each angle of the triangle​

Answer 1

Step-by-step explanation:

let base angles will be x

base angles are x,x

vertex angle is 3x

according to question.

x+x+3x= 180° ( angle sum property)

5x= 180°

x= 180/5

x= 36 °

base angles are 36°,36°

vertex angle is 3x= 3× 36= 108°
