A gun is kept on an inclined plane . The maximum ranges up and down the plane are 250 m and 750 respectively Then find the angle of inclination of the inclined plane.

Explanation

To solve the problem of finding the angle of inclination of the inclined plane given the maximum ranges up and down the plane, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Problem**:
- We have a gun placed on an inclined plane.
- The maximum range of the gun when fired up the incline is \( R_{up} = 250 \, \text{m} \).
- The maximum range of the gun when fired down the incline is \( R_{down} = 750 \, \text{m} \).
