Step-by-step explanation:

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.

So, 25^{\circ}+x=70^{\circ}25

∘

+x=70

∘

x=70^{\circ}-25^{\circ}x=70

∘

−25

∘

x=45^{\circ}x=45

∘

Hence the measure of the other interior angle is 45°
