How to use the law of cosines to find the missing parts of a triangle

The video tutorial explains how to determine the largest side or angle using the Law of Cosines. It provides a detailed calculation of angle B, followed by the use of the Law of Sines to find angle C, considering both acute and obtuse possibilities. Finally, it demonstrates how to calculate angle A using the angle sum property, ensuring the sum of angles equals 180 degrees.
