Though I passed I'm hazy at maths. Like computing - got a degree in Computer Science and still fumble around witht he basics ;)
On paper, angle=cos(Adjacent/Hypotenuse), but that wasn't working. So I swapped out Cos with Sin (which you always try when it isn't working as they're pretty much the same thing offset slightly!) and it worked. But I still don't know why!
