Find the missing sides of a triangle using the law of sines

The video tutorial explains how to use the law of sines to solve for unknown sides and angles in a triangle. It begins with setting up a ratio using known angles and side lengths, then demonstrates solving for side B. The tutorial continues by finding angle A using the sum of angles in a triangle and concludes with solving for side A using the established ratio. The instructor emphasizes the importance of using the correct mode on the calculator and provides step-by-step calculations.

Explain how to use the ratio of sides and angles to find side A.

What is the final calculated value of side A?
