Question

Aicharya · Accepted Answer

Direction cosines of a line are given as $\left\langle-\frac{9}{11}, \frac{6}{11},-\frac{2}{11}\right\rangle$ respectively, so the direction ratios are $-9,6,-2$ respectively. Hence, option (c) is correct.

The direction cosines of a line are \(\left\langle\frac{-9}{11}, \frac{6}{11}, \frac{-2}{11}\right\rangle\)…
