How to use the law of sines to find the missing measurements of a triangle

The video tutorial explains how to solve a non-right triangle problem using the law of sines. It begins by identifying that the triangle is not a right triangle, thus requiring the use of the law of sines or cosines. The tutorial demonstrates how to find the length of side B using the law of sines and cross multiplication. It then calculates angle A using the sum of angles in a triangle. Finally, it uses the law of sines again to find side A and verifies the results for reasonableness.

What is the value of angle A after applying the triangle angle sum property?

Describe the process of finding side A using the proportion set up in the problem.

What is the final conclusion about the side lengths in the triangle?
