Trigonometry: How to find side lengths

We discuss how to use the trigonometric ratios that we learnt in a previous video to solve questions with a missing side length. We use sin, cos and tan in the correct trig equation after labelling our right-angled triangle to solve these questions. There are worked examples throughout the video.
