Question

each of the two equal angle of an isoscels triangle is twice the third angle . find the angle of the triangle

Answer 1

let the vertex angle or third angle be x degrees
therefore, each base angles=2x

angle sum property of a triangle is 180 degrees
thus, x+2x+2x=180
5x=180
x=36 degrees

therefore, 2x=72 degrees

thus the angles of triangle are 36, 72, 72 

Answer 2

hii frnd...

As it is an isosceles triangle so base angles will be equal.
So, let the third angle be x.
As it is 2 times the third angle so the base angles will become 2x + 2x

Using triangle sum property
2x + 2x + x= 180
5x = 180
x = 36

Third angle = 36
Base angles = 72 (each)

Hope it helped u!!!
