Applying the law of cosines when given SAS

The video tutorial explains the application of trigonometric laws to solve a triangle problem. Initially, the law of sines is considered but found inapplicable due to insufficient data. The focus shifts to the law of cosines, which is used to calculate a side length. Once the side is determined, the law of sines is applied to find the remaining angles of the triangle. The tutorial provides a step-by-step approach to solving the problem, emphasizing the importance of selecting the appropriate trigonometric law based on available data.
