An observer 1.5 metres tall is 20.5 m away from a tower 22 metres high. Determine the angle of elevation of the top of the tower from the eye of the observer.

Explanation

To solve the problem, we need to determine the angle of elevation of the top of the tower from the observer's eye level. Here’s a step-by-step solution:

### Step 1: Understand the problem
We have an observer who is 1.5 meters tall, standing 20.5 meters away from a tower that is 22 meters high. We need to find the angle of elevation from the observer's eye level to the top of the tower.

### Step 2: Calculate the height from the observer's eye level to the top of the tower
The height of the tower is 22 meters, and the height of the observer is 1.5 meters. Therefore, the height from the observer's eye level to the top of the tower is:
