Question

Oe of the exterior angles of a triangle is 100*.The interior opposite angles are equal to each other .Find the masure of these equal interior opposite angles.

Answer 1

Hi there!!!

Exterior angle = sum of two opposite interior angle.

Let opposite interior angles be x.

100° = x + x

100° = 2x

$\bf{\frac{100}{2} = x}$

50° = x

Measure of two opposite angles is 50° each.
