Question

In an isoceles triangle ,the vertex angle is twice the sum of the base angles .Find the angles of a triangle​

Answer 1

Step-by-step explanation:

let the base angle be x

vertex angle=2x

sum of isoceles triangle be90

atq

x+2x=90

3x=90

x=90/3

x=30

base angle be 30

vertex angle be 60

sum of angle of triangle be180
