The direction cosines of a line are \(\left\langle\frac{-9}{11}, \frac{6}{11}, \frac{-2}{11}\right\rangle\) respectively. Then its direction ratios are
- A \(\langle 9,6,-2\rangle\)
- B \(\langle-9,-6,2\rangle\)
- C \(\langle-9,6,-2\rangle\)
- D \(\langle 9,-6,-2\rangle\)
Answer & Solution
Correct Answer
(C) \(\langle-9,6,-2\rangle\)
Step-by-step Solution
Detailed explanation
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.
