Question

The value of x + y in the given figure is

• A. 120${}^{\circ }$
• B. 60${}^{\circ }$
• C. 180${}^{\circ }$

Answer 1

The correct option is A 120${}^{\circ }$

By angle sum property of triangle,
$\angle A$ + $\angle B$ + $\angle C$ = 180${}^{\circ }$
$\Rightarrow$ x + y + 60= 180
$\Rightarrow$ x + y = 180 - 60
$\Rightarrow$ x + y = 120${}^{\circ }$
