Question

this image has rotational symmetry. what is the smallest number of degrees you need to rotate the image for it to look the same?

Explanation:

Step1: Count the number of spokes

Count the visible spokes on the wheel: 16

Step2: Calculate rotation angle

Divide full rotation (360°) by spoke count:
$\frac{360^\circ}{16} = 22.5^\circ$

Answer:

$22.5$
