Law of Cosines | Find all the missing measures | SSS

The video tutorial explains how to solve a triangle problem using the law of cosines and the law of sines. It begins by setting up the problem with given side lengths and discusses why the law of cosines is necessary. The tutorial then demonstrates how to calculate the largest angle, angle C, using the cosine formula. After finding the largest angle, the law of sines is used to find the remaining angles, with a focus on avoiding rounding errors. The video concludes with tips on using these trigonometric laws effectively.
