Try to identify what your real problem is, so that you can ask the really important questions. For example, if you just ask: "How do I answer this question?", your teacher might say: "Well, we need to use the cosine of this angle . . , etc." You might understand everything he/she says but the next time you see a fairly similar question you've still not got a clue as to whether you should use the sine, cosine or tangent (or even if Pythagoras might be of more assistance). The really important question isn't: "How do I answer this question?; it's: "How do you know whether to use the sine, cosine or tangent? Can you tell me how to see which one I should use?".
Keep asking questions but remember that if your teacher says something like "Well, it's a tangent here ...", you should respond with "How do you know?" Even the best teachers sometimes take prior knowledge for granted. They need prodding to remind them that not everyone finds maths as easy as they do ;-)
Lastly, if you're really stuck with something, post your question here on AB. (If it involves using symbols and equations which are hard to type out, write it out, scan it and put it on Tinypic.com. Just post a link to your image here). We'll do our best to explain things.
