Word problem find the distance between two towns with trig

The video tutorial guides students through solving a geometry problem involving an airplane at a 10 km altitude observing two towns. The teacher explains how to draw the scenario, understand angles of depression, and create right triangles. Using trigonometry, specifically the tangent function, the teacher calculates the distances to determine how far apart the towns are. The session concludes with a Q&A.
