I just couldn't picture what was happening here until I noticed that you'd included an image with your verbal question.  My bad!  

I do suggest you try to paraphrase this question, stating in your own words which steps you must follow to find which quantities.  Also:  copy that diagram down and mark it up with the dimensions given.
