Question

Find the complement of the following angles:
${63}^{\circ }$.

• A. ${27}^{\circ }$
• B. ${54}^{\circ }$
• C. ${117}^{\circ }$
• D. None of these

Answer 1

The correct option is A ${27}^{\circ }$

We know, two angles are complementary when their sum is equal to ${90}^o.$

Given, measure of one angle is ${63}^o.$

$\Rightarrow$ Measure of its complementary angle $={90}^o-{63}^o$ $={27}^o.$

$\therefore$ Measure of complementary angle of ${63}^o={27}^o$.

Option $A$ is correct.
