Question

an exterior angle of a triangle is 75 degree and its two interior angle or equal each of these equal angle is

Answer 1

According to exterior angle property

Exterior angle = Sum of interior opposite angles

So let the interior opposite angle be x. It is given both the angles are equal.
So , x + x = 75
2x = 75
x = 37.5°

So your required answer is D) 37.5°

Hope This Helps You!

Answer 2

We know that Sum of opposition interior angles = Exterior angle.

Given the interior angles are equal, say A

& Exterior angle=75°

A+A=75°

A=37.5°

So, the equal interior angles measure 37.5°

Required answer is Option d
