Question

Write the measure of the complementary angle in each of the following.

$$\begin{gathered} \left(i\right){30}^o \\ \left(ii\right){52}^o \\ \left(iii\right){18}^o \\ \left(iv\right){64}^o \end{gathered}$$

Answer 1

If the sum of two angles is equal to ${90}^o$, then these two angles can be termed as complementary angles.

(i) Complementary angle of ${30}^o$ $={90}^o-{30}^o={60}^o$

(ii) Complementary angle of ${52}^o$ $={90}^o-{52}^o={38}^o$

(iii) Complementary angle of ${18}^o$ $={90}^o-{18}^o={72}^o$

(i) Complementary angle of ${64}^o$ $={90}^o-{64}^o={26}^o$
