Given:

One angle of isosceles triangle = 110°

It is an isosceles triangle. So, two angle of it must be equal, we know sum of all angles of triangle is 180° . That means there are two equal angles other than 110° angle.

Let the equal angles be x

Then, x + x + 110° = 180

2x = 180° - 110°

2x = 70°

x = 70°/2

x = 35°

 

Thus, there are two angles each of 35° in this triangle.
