CBSE 12th Mathematics Delhi Set 1 - 2023 | Three Dimensional Geometry Question 5 | Mathematics

If a line makes angles of $$90^{\circ}, 135^{\circ}$$ and $$45^{\circ}$$ with the $$x, y$$ and $$z$$ axes respectively, then its direction cosines are:

$$0,-\frac{1}{\sqrt{2}}, \frac{1}{\sqrt{2}}$$

$$-\frac{1}{\sqrt{2}}, 0, \frac{1}{\sqrt{2}}$$

$$\frac{1}{\sqrt{2}}, 0,-\frac{1}{\sqrt{2}}$$

$$0, \frac{1}{\sqrt{2}}, \frac{1}{\sqrt{2}}$$
