A universal bevel protractor will measure an angle to within a couple minutes of a degree. They work well for doing accurate layout work, but are probably a bit of overkill for that. They can also be used to set a part in a vise or on an angle plate to a very precise angle, but take a good amount of skill to use effectively. In short, they tend to spend more time in their cases than in actual use, so I would suggest spending the money on a sine bar and a set of gauge blocks instead. It's a much better way to set an angle.
