Find the direction cosines of the line passing through the two points `( 2, 4, 5)`and `(1, 2, 3)`.

Explanation

To find the direction cosines of the line passing through the points \( A(2, 4, 5) \) and \( B(1, 2, 3) \), we can follow these steps:

### Step 1: Determine the Direction Ratios
The direction ratios of a line passing through two points \( A(x_1, y_1, z_1) \) and \( B(x_2, y_2, z_2) \) can be calculated using the formula:
\[ (x_2 - x_1, y_2 - y_1, z_2 - z_1) \]
