Calculating Missing Angles and Side Lengths in Non-Right Angle Triangles

The video tutorial explains how to find missing angles and side lengths in non-right angle triangles using the sine and cosine rules. It covers when to use each rule, provides examples, and demonstrates the process of solving for missing values. The sine rule is used when an angle and its opposite side are known, while the cosine rule is applied when two sides and the included angle or all three sides are known. The tutorial emphasizes the importance of understanding and rearranging formulas to find missing values.
