Our optimal angle was 34 degrees. which leads us to:
In geometry an angle is measured in degrees, where a full circle is 360 degrees. As in the figure above, a smallish angle might be around 30 degrees. For very small angles, the degree is further divided in to 60 minutes. For even smaller measurements the minute is divided again into 60 seconds, However this last measure is so small, it only used where angles are subtended over extreme distances such as astronomical measurements, and measuring latitude and longitude.
Great job on your blog. Your pictures matched really well with your information. I think that the angle you chose was very percise in what you believe would make your cannon fire.
