How to use the law of sines when given two angles and one side

The video tutorial explains how to solve a triangle problem using the law of sines. It begins with setting up the problem and understanding the law of sines. The instructor then calculates the missing angle using the given angles and applies the law of sines to find the side lengths. The tutorial concludes with final calculations and verification of the results, ensuring the angles add up to 180 degrees and the side lengths make sense.
