Question

Find the value of x (in degrees) from the given figure.

• A. 32

Answer 1

The correct option is A 32
$\text{From the figure, the angles, 2x and}\text{(3x+20)° are co interior angles.}\text{Hence, they are supplementary.}$

$\Rightarrow 2x+(3x+20)°=180°\Rightarrow 2x+3x=180°-20°\Rightarrow 5x=160°\Rightarrow x=32°$
