Question

The measure of an angle is $3$ times its supplement. Find the angle.

Answer 1

As we know that two angles are said to be supplement if and only if their sum is ${180}^{\circ }.$

Suppose if one angle is $x$ then the other angle will be $3x$ then

$x+3x={180}^{\circ }$

$4x={180}^{\circ }$

$x={45}^{\circ }$

Hence, the first angle is ${45}^{\circ }$ and other is ${135}^{\circ }.$
