Using tangent to find the missing length of a triangle

The video tutorial explains how to work with right triangles by identifying the hypotenuse, adjacent, and opposite sides. It introduces trigonometric functions—sine, cosine, and tangent—and demonstrates how to use the tangent function to solve for an unknown side length when given an angle and one side. The tutorial includes a practical example using a 52-degree angle and an adjacent side of 13 units, leading to a calculation of the opposite side using a calculator.
