Thread: Maths Problem Solving Advice

Hi, I'm not really too sure where to post this question, but I need some advice or some strategies on how to approach problem solving questions in the pdf below. If anyone knows any good techniques or has any advice, that would be greatly appreciated. Thanks.

Now you have not only an answer, but a clue to all problems that have 2a in them.

Does that help you?

I don't know if the answer should be in radians or degrees, but you get the point.
