This video tutorial explains how to use trigonometric ratios to solve for the sides of right triangles. It covers the three main trig ratios: sine, cosine, and tangent, and provides step-by-step examples of how to apply these ratios to find missing sides. The video also emphasizes the importance of setting calculators to degree mode to ensure accurate results.
