Question

Find the value of $x$ in the figure given below.

• A. ${60}^{\circ }$
• B. ${45}^{\circ }$
• C. ${30}^{\circ }$
• D. ${90}^{\circ }$

Answer 1

The correct option is C ${30}^{\circ }$

$x+3x+2x={180}^{\circ }$ {sum of angles on a straight line is ${180}^{\circ }$}
$6x={180}^{\circ }$
$x=\frac{{180}^{\circ }}{6}$
$x={30}^{\circ }$
