If someone could help me with this problem it would be greatly appreciated!: Roberto folds a circular piece of paper as shown. When he unfolds the paper, how many different-sized central angles (less than 360º) are formed? (Enter only the number.) Picture of problem: http://i49.tinypic.com/os6ayr.png.
