Question

In the given figure, the value of $(\angle x+\angle y)$ is :

• A. ${110}^0$
• B. ${100}^0$
• C. ${120}^0$
• D. ${60}^0$

Answer 1

The correct option is B ${100}^0$

An exterior angle of a triangle is equal to the sum of the opposite interior angles

$\therefore \angle x+\angle y={100}^{\circ }$

So option $B$ is correct.
