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? 12 30 36 40 60

Explanation:

Step1: Count the number of spokes

The wheel has 12 spokes.

Step2: Calculate the angle of rotation for symmetry

A full - rotation is 360 degrees. To find the smallest angle of rotation for which the image looks the same, we divide 360 by the number of spokes. So, $\frac{360}{12}=30$ degrees.

Answer:

B. 30
