Question

Write the measure of the supplementary angle of the given angle:
${112}^{\circ }$.

Answer 1

Let the measure of the supplementary angle of ${112}^{\circ }$ be $x.$

As we know that the sum of supplementary angles is equal to ${180}^{\circ }.$ So,

${112}^{\circ }+x={180}^{\circ }$

$\Rightarrow x={180}^{\circ }-{112}^{\circ }$

$\Rightarrow x={68}^{\circ }$

Thus, the supplementary angle of given angle is ${68}^{\circ }.$
