Learn how to solve using the law of cosines

The video tutorial explains how to solve a triangle problem using the Law of Cosines and the Law of Sines. It begins with setting up the problem by identifying the side lengths and then proceeds to calculate the largest angle using the Law of Cosines. After determining angle C, the tutorial demonstrates how to find the other angles using the Law of Sines and the angle sum property of triangles. The process is summarized with emphasis on the importance of calculating the largest angle first.
