Question

In an isosceles triangle the base angles are equal.vertex angle is 108.what are the base angles of triangle

Answer 1

Answer:

Base angles are of 36 degrees each.

Explanation:

As we know the sum of all angles of a triangle is 180.

Vertex angle is known which is 108 degrees. as base angles are equal let them 2x.

so, 180-2x=108

180-108=2x

2x=72

x=72/2

x=36 degrees .
