Using inverse tangent to solve for the missing angle of a triangle

The video tutorial explains how to find a missing angle in a right triangle using trigonometry. It emphasizes identifying the correct trigonometric function based on given information, specifically focusing on the tangent function when the hypotenuse is not provided. The tutorial demonstrates solving for the angle Theta using inverse operations and a calculator, converting the result into degrees. Students are encouraged to practice similar problems to reinforce their understanding.
