Question

Find the value of 'x' from the figure.

• A. 135°
• B. 165°
• C. 90°
• D. 95°

Answer 1

The correct option is A

135°

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${}^{\circ }$
