Using inverse trig properties to solve word problems - Math help

The video tutorial explains how to solve a geometry problem involving the Earth and a satellite. It sets up a right triangle using the Earth's radius and the satellite's distance. The tutorial demonstrates how to calculate the angle of depression using trigonometric functions, specifically the sine function, and verifies the results. The process involves finding angle Theta and then determining the angle of depression by subtracting from 90 degrees.
