Question

Sushma says, "Complementary angle of ${48}^0$ is ${42}^0$". Do you agree with her? Give reasons.

Answer 1

We know, two angles are said to be complementary, if the sum of their measures is ${90}^{\circ }.$

Given, the angles are ${48}^o$ and ${42}^o$.

Then, their sum $={48}^o+{42}^o={90}^o$.

Therefore, they are complementary.

Hence, Sushma is right.
