Question

Find the value of 'x' from the figure.

• A. 135${}^{\circ }$
• B. 165${}^{\circ }$
• C. 90${}^{\circ }$
• D. 95${}^{\circ }$

Answer 1

The correct option is A

135${}^{\circ }$

Since both angles form a linear pair, their sum will be equal to 180${}^{\circ }$.
So, x${}^{\circ }$ + 45${}^{\circ }$ = 180${}^{\circ }$
x${}^{\circ }$ = 180${}^{\circ }$- 45${}^{\circ }$
x = 135${}^{\circ }$
