Measure of an angle is given below. Find the measure of it's complementary angle:

${58}^o$.

We know, two angles are complementary when they add up to ${90}^o.$

Given, measure of one complementary angle is ${58}^o.$

$\Rightarrow$ Measure of other complementary angle $={90}^o-{58}^o$ $={32}^o.$

Hence, measure of the complementary angle of ${58}^o$ is ${32}^o$.
