If a line makes angles `90^o,135^o,45^o`with the x, y and z-axes respectively, find its direction cosines.

Explanation

To find the direction cosines of a line that makes angles of \(90^\circ\), \(135^\circ\), and \(45^\circ\) with the x, y, and z axes respectively, we can follow these steps:

### Step 1: Identify the angles
Let:
- \(\alpha = 90^\circ\) (angle with the x-axis)
- \(\beta = 135^\circ\) (angle with the y-axis)
- \(\gamma = 45^\circ\) (angle with the z-axis)
