The video tutorial demonstrates how to use the law of sines to solve trigonometric word problems. It begins with an introduction to the law of sines and the importance of setting up triangles. The first example involves calculating the height of the Leaning Tower of Pisa using given angles and distances. The second example calculates the distance from a ship to a lighthouse using angles measured from the shore. The tutorial emphasizes the importance of correctly labeling triangle components and using the law of sines formula to find missing lengths or angles.
