Chapter E, Problem 2.8EX

To determine

To Find:

The complementary angles.

Answer to Problem 2.8EX

The complementary angles are option (b) $\angle 3$ and $\angle 4$ .

Explanation of Solution

Given information:

If $T\overline{Q}\perp Q\overline{R}$ in the given figure.

If $T\overline{Q}\perp Q\overline{R}$ , then the angle

  $\begin{array}{l}\angle TQR={90}^{\circ }\\ \angle 3+\angle 4={90}^{\circ }\end{array}$

Two angles are said to be complementary angles when the sum of their angles are ${90}^{\circ }$ (Right angled triangle).

Therefore, the complementary angles are option (b) $\angle 3$ and $\angle 4$ .
