Just the cosine rule.

Finding the side
Finding the angle

Example problem pairs (see https://berwickmaths.com/ for an explanation of this) and some questions.

Not much of putting it all together but a quick exercise in picking which rule to use.

There is an exam question included, a hard one that involves using cosine and then basic trig to find an angle.

I did this over two lessons. Finding the side was one lesson, finding the angle the next lesson
