Question

an exterior angle of a triangle is 100 degree and its interior opposite angles are equal to each other find the measure of each angle of the triangle

Answer 1

Since we know that sum of 2 opposite interior angles is equal to exterior angle.
So, let one int. angle=x
& other int. angle=x
So, x+x= 100
2x=100
x=100/2
x=50
Therefore, each interior angle = 50°

Answer 2

80°,50°,50°
