This video tutorial covers solving problems using right angle triangles and trigonometric ratios. It includes examples such as calculating a tree's height from its shadow, determining the angle of inclination of Baldwin Street, finding the height of a cherry picker platform, and calculating the angle of a gable roof. Each example demonstrates how to isolate and draw a right angle triangle from given information and apply the appropriate trigonometric ratio to solve the problem.
