Master Solving for the missing parts of a triangle using the law of cosines SAS

The video tutorial explains how to find missing parts of a triangle using the law of cosines and the law of sines. It begins with identifying the type of triangle and determining the appropriate law to use. The instructor demonstrates the calculation of side lengths using the law of cosines and then explains how to find angles using the law of sines, addressing the ambiguous case. The tutorial emphasizes the importance of understanding the order of operations and provides a detailed walkthrough of the calculations involved.
