Question

An exterior angle of a triangle is 72 degree and 2 opp. Interior angle are equal. Find each of these angle

Answer 1

2x = 72

z= 36

Angles are 36, 36

Answer 2

Answer:

according to angle sum property of a triangle sum of two interior angle =exterior angle

Therefore according to the question exterior angle =72

And let the same interior angle be x+x=2x

Solving

x+x=72

2x=72

x=72/2

x=36

Therefore interior angles are 36 and 36 degree
