Question

An exterior angle of a triangle is of measure 70 degree and one of its interior opposite angles is of measure 25 degree. Find the measure of the other interior opposite​

Answer 1

Answer:

$\boxed{45^{o} }$  

Step-by-step explanation:

Given:

• Exterior angle of a triangle= 70°

• One of the interior opposite angle of Triangle= 25°

To Find:

The measure of the other interior opposite​ = ?

Solution:

Let the  measure of the other interior opposite​ = x°

→Exterior angle = The sum of the two interior opposite angles

⇒70° = x° + 25°

⇒70° - 25° = x°

⇒x° = 45°

∴The measure of the other interior opposite​ = $\boxed{45^{o} }$
