Find the missing measures, law of cosines then law of sines

The video tutorial guides students through solving a triangle problem by using the law of cosines and sines. It emphasizes the importance of solving for the largest angle first to avoid errors and demonstrates how to use inverse functions to find angles. The tutorial also covers the process of calculating the remaining angles and addresses common mistakes in rounding and calculator usage.

What is the relationship between the sides of a triangle and the angles opposite those sides?

What are the potential errors one might encounter when using the law of sines for triangles with an obtuse angle?

How do you determine if an angle in a triangle is obtuse or acute based on the side lengths?
