Trigonometric Functions and Triangle Properties

The video tutorial explains how to find an angle in a right angle triangle using the SOH formula. It begins by introducing the problem and labeling the sides of the triangle as opposite, adjacent, and hypotenuse. The tutorial then applies the sine function (SOH) to solve for the angle X, using the given side lengths. Finally, it demonstrates how to calculate the angle using the inverse sine function and a calculator, resulting in an angle of 42.84 degrees.
