Question

Find the complement of each of the following angles:
(i) 35°
(ii) 72°
(iii) 45°
(iv) 85°

Answer 1

Two angles are called complementary angles if the sum of those angles is 90°.

Complementary angles of the following angles are:

$$\begin{gathered} \left(\mathrm{i}\right)90°-35°=55° \\ \left(\mathrm{ii}\right)90°-72°=18° \\ \left(\mathrm{iii}\right)90°-45°=45° \\ \left(\mathrm{iv}\right)90°-85°=5° \end{gathered}$$
