This is the next video in the series looking at Year 9 Triginometry. In. the previous videos, I looked at how to find the length of missing sides when we are given one side and an angle. Now we look at how we can find a missing angle when we are given two side lengths in a right angled triangle. There are worked examples to help explain the theory in an easy to understand way. Oh, and some humour of course!

There are no current errors with this video ... phew!
