Determine the remaining parts of a triangle using the law of sines

The video tutorial explains how to solve a triangle problem using the Law of Sines. It begins by identifying the type of triangle and then applies the Law of Sines to find missing side lengths and angles. The tutorial demonstrates calculating side B using given angles and the sine function, followed by finding angle C using the angle sum property. Finally, it calculates side C using known values and the Law of Sines.
