Not a particular problem to wonder about but more of a general question, when one has a free body diagram, when is it best to use sine and when is it best to use cosine?

I am reviewing some of my tests for a final, and having previously re-read my forces chapter, I thought that angles rising from the x-axis used sine and angles 'rising' from the y-axis used cosine. However, I have found multiple exceptions to both of these conceptions.

So when is it best to use one or the other?
