Question

one of the exterior angle of a triangle is 100 degree and it's interior opposite angles are equal. what will be the measure of each of these interior angles of the triangle, one is double the other. find the angles

Answer 1

Given: One of the exterior angles is 100° and interior angles are equal to each other.

To find: The measures of the interior angles.

Answer:

Sum of 2 interior angles is equal to an exterior angle.

Let the interior angle be x.

Since the  interior angles are equal to each other (given), 2x = 100°

x = 100°/2

x = 50

Therefore, the measure of 2 interior angles is 50°.

Hope it helps :)
