Question

In an exterior angle of a triangle is 135 and one of the interiro opposite angle is 55, find the interiro opposite angle

Answer 1

ANSWER:

STEP BY STEP EXPLANATION

In a triangle, an exterior angle is equal to the sum of two opposite exterior angles.

So,

Exterior angle = First interior angle + Second interior

angle

Given Exterior angle = 135°

First interior angle = 55°

Let Second interior angle be x

Then,

135° = 55° + x

Therefore, x = 135° - 55°

So, x = 80°

So, Second interior angle is 80°
