The angle of rotation of a polygon is found using the formula 360/n

Where n is the number of sides.

Shape 1: 360 / 10 = 36

Shape 2: 360 /4 = 90

Shape 3: 360 /5 = 72

Shape 4: 360/8 = 45

Shape 5: 360/3 = 120

Shape 6: circles = 1

Shape 7: 360 /6 = 60

Shape 8: 360 / 12 = 30

There are 3 shapes that are 72 or higher.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
