Question

an exterior angle of a triangle is 115 and its two interior opposite angles are equal, then find the measure of each equal angle

Answer 1

Hey mate!

Remember a rule,

Exterior angle is equal to the sum of the interior opposite angles.

Let one of the interior opposite angle be x

Therefore the second angle will also be x.

So,

x+x=115°

2x=115°

x=115°/2

x=57.5°
