4g Example 4 (Find the missing Angle of a triangle)

The video tutorial covers the use of inverse trigonometric functions to find angles in trigonometry. It explains the concept of inverse functions, particularly focusing on sine, cosine, and tangent inverses. The tutorial demonstrates how to solve for angles using these functions and emphasizes the importance of using technology, such as calculators, to find values not on the unit circle. The video also highlights the need to distinguish between degrees and radians when calculating angles.
