Question

In an isosceles triangle, the base angles are equal, the vertex angle is thrice of either the
base angles. What are the degrees major of the angles of the triangle?​

Answer 1

Step-by-step explanation:

let the base angles be x

so vertex angle = 3x

by angle property of traingle

angle a+angle b + angle c=180°

x+x+3x=180°

5x=180°

x=180/5

x= 36°

so each base angles are of 36° and vertex angle is 3x

3 X 36 = 108
