How to Find the Missing Angle Using Inverse Sine Triangle

The video tutorial explains how to find the angle Theta in a right triangle using trigonometry. It begins by identifying the sides of the triangle: hypotenuse, adjacent, and opposite. The sine function is chosen to relate the opposite side to the hypotenuse. To solve for Theta, the inverse sine function is used. The tutorial also covers how to use a calculator to find the sine inverse and discusses the concept of approximation for the result.
