Find the measure of an angle use inverse tangent

The video tutorial explains how to find the angle X when given the tangent of X equals 1.5399. It starts by ensuring the use of the tangent function with a right triangle. The tangent function is described as a ratio of the opposite side to the adjacent side of a triangle. The tutorial then introduces the concept of inverse functions, specifically the inverse tangent, to find the angle X. The process involves using a scientific calculator to compute the inverse tangent of 1.5399, resulting in an angle of 57 degrees.

Explain the concept of inverse functions in relation to the tangent function.
