Question

An exterior angle of a triangle is equal to ${100}^{\circ }$ and two interior opposite angles are equal. Each of these angles is equal to:

Answer 1

In a triangle, exterior angles is equal the sum of its interior opposite angles

$\therefore$ Sum of interior opposite angles =${100}^{\circ }$

$\because$ Both angles are equal

$\therefore$ Each angle will be = $\frac{{100}^{\circ }}{2}={50}^{\circ }$
