Find the degree of rotation about the spinner center that maps label i to label g.

A circle has 360°. 
The given circle is divided by 10 parts.

360°/10 = 36° per part

If clockwise is used to rotate the spinner from label i to label g. Then,

36° x 8 = 288°

If counterclockwise is used to rotate the spinner from label i to label g. Then,

36° x 2 = 72°
