33/100 as a decimal is 0.33
I think it is C. 60.
You can eliminate A because it is not a right angle, and D because the angle is bigger than the given angle. So it is between 50 and 60, and I hope this is right and the picture makes sense

360°÷n = number of sides of a regular polygon.
n= one of the exterior angle of a regular polygon.
180°-60°=120°
n=120°
360°÷120°= 3
Zero is an integer but not a natural (counting) number.
Most square roots of integers are not rational numbers.
√2, √3, √5, √6, √7, and (pi) are real, irrational numbers.
