Trigonometry and Geometry Problem Solving

The video tutorial explains a sailing boat problem involving a race with three legs. It guides through calculating distances between points using trigonometry and geometry. The teacher emphasizes the importance of diagrams and naming points for clarity. The tutorial covers finding distances B north of A, C south of B, and C south of A, using angles and right triangles, and concludes with using rectangle properties to solve the final part.
