Word Problems with trigonometry and triangles

The video tutorial explains how to solve a geometry problem involving the angle of depression. It begins by introducing the problem, which involves a boat and a dock, and explains the concept of the angle of depression. The tutorial then sets up a right triangle to model the problem and uses trigonometry, specifically the tangent function, to calculate the distance from the dock to the boat. The solution is demonstrated step-by-step, concluding with the final answer.

Explain how to create a right triangle using the angle of depression.

What trigonometric function is used to find the distance of the boat from the dock?
