Solving Right Triangle Trigonometry Word Problems

This video tutorial covers modeling real-world situations using trigonometry. It includes examples such as calculating the distance of a zipline cable, the length of a skateboard ramp, the altitude of a drone, the angle of elevation for an anti-aircraft tank, and the distance traveled by a boat approaching a lighthouse. Each scenario uses trigonometric functions like cosine, sine, tangent, and inverse tangent to solve for unknown values.
