A bridge across a river makes an angles of `45^0` with the river bank as shown in Figure. If the lengthof the bridge across the river is 150m, what is the width of the river?

Explanation

To find the width of the river given that the bridge makes an angle of \(45^\circ\) with the river bank and has a length of 150 meters, we can use trigonometric principles.

### Step-by-Step Solution:

1. **Understanding the Problem**:
- We have a right triangle formed by the bridge, the width of the river, and the vertical height from the end of the bridge to the river bank.
- The angle between the bridge and the river bank is \(45^\circ\).
