Keep in mind that there are 360 degrees in a full circle...
...so 10% would be 36 degrees.
All a protractor does is measure the number of degrees in an angle (which in turn tells you what percent of a circle it is).
If you want an angle that is 1/2 a circle, then you need 180 degrees. No coincidence that 180 degrees is a straight line...look at the angle you get with a semicircle....straight.
1/3 circle = 120 degrees = 33.33%
1/4 circle = 90 degrees = 25%
1/5 circle = 72 degrees = 20%
1/6 circle = 60 degrees = 16.67 %
1/8 circle = 45 degrees = 12.5%
1/9 circle = 40 degrees = 11.11%
1/10 circle = 36 degrees = 10%
1/12 circle = 30 degrees = 8.33%
