FINAL ANSWER

-The measure of the other interior angle

is 45°

STEP BY STEP EXPLANATION

Given- Exterior angle of triangle is 70°

           One of its interior opposite angles is 25°

To Find :Find the measure of the other interior angle.

Solution:

Let the measure of the other interior angle be x .

Exterior angle property of triangle : The sum of measures of two opposite interior angles of triangles is equal the measure of exterior angle.

Hence the measure of the other interior angle is 45°
