Understanding Bearings and Distances

The video tutorial covers the process of calculating distances and bearings using trigonometry. It begins with an introduction to distance calculation, followed by determining the total distance east from point X to Z. The tutorial then discusses vertical distances and updates the diagram accordingly. The final part involves solving a question about bearings, including calculating the bearing from X to Z. The session concludes with a summary of the bearings question, emphasizing the importance of understanding angles and lengths in such problems.
