How to find the area of an oblique triangle

The video tutorial guides students through solving a triangle problem using trigonometry. It begins by setting up the problem and identifying known values. The teacher applies the triangle angle sum theorem to find a missing angle and uses the sine rule to calculate side lengths. The tutorial emphasizes the importance of using precise values in calculations and demonstrates how to calculate the area of the triangle. The session concludes with verification of results and a discussion on alternative methods.

What are the implications of using different angles in the sine ratio when calculating side lengths?

Why is it important to store calculated values in a calculator when solving problems?
