Question

1.)an exterior angle of a triangle is measured 70° and one of its interior opposite angles is of measure 25°. find the the measure of the other interior opposite angle.

Answer 1

Step-by-step explanation:

Given that :

The measure of an exterior angle in a triangle=70°

The measure of its opposite interior angle=25°

Let the other interior angle be x°

We know that" the exterior angle in a triangle is equal to the sum of opposite interior angles".

=>70°=25°+x°

=>x°+25°=70°

=>x°=70°-25°

=>x°=45°

The measure of the other opposite interior angle is 45°
