Question

Find complementary angle of ${23}^{\circ }$.

Answer 1

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

Given, measure of one complementary angle is ${23}^o.$

$\Rightarrow$ Measure of other complementary angle $={90}^o-{23}^o$ $={67}^o.$

$\therefore$ Measure of a complementary angle of ${23}^o={67}^o$.
