How to solve a word problem using trigonometry

The video tutorial explains how to solve a problem involving a pilot needing to land early due to a storm. The problem requires finding the angle of depression for the landing. The teacher explains the concept of angle of depression, draws a right triangle to represent the situation, and uses trigonometry, specifically the tangent function, to calculate the angle. The solution involves using the inverse tangent function to find the angle, which is approximately 14.79 degrees.

Which trigonometric function is used to find the angle of depression in this scenario?

What is the final calculated angle of depression for the pilot?
