The angle of elevation of the ground is the angle between the ground and the line of sight
The angle of elevation of the ground is 30.46 degrees
<h3>How to calculate the angle of elevation</h3>

Evaluate the quotient
Take the arc tan of both sides
Using a calculator, we have:
= 30.46
Hence, the angle of elevation of the ground to the nearest tenth of a degree is 30.46 degrees
