Question

one of the exterior angles of a triangle is 100 degree and its interior opposite angle are equal to each other what is the measure of each of these two angles​

Answer 1

Answer:

The exterior angle sum property of a ∆ states that the sum of two opposite angles of a ∆ is exactly equal to the exterior angle...

Answer 2

Answer: The measure of each of these two interior angles will be 50° .

Step-by-step explanation:

Given , in ∆ ABC , in which the side BC is extended outwards till point R.

Angle A = Angle B = x

Also, Angle ACR = 100°

we know that ,

Exterior angle of triangle = the sum of the opposite interior angles of the triangle .

Therefore , Angle ACR = Angle A + Angle B

100° = x + x

That implies x = 50° .
