Help?!!

what is the measure of a counterclockwise rotation about the spinner center that maps label i to label f

Answer 1

Answer: 108 DG

Step-by-step explanation: Just took the test!

Answer 2

We have to rotate spinner 108 degree counterclockwise to label i to label f.

Explanation:

From the figure it is noticed that number of parts of spinner is 10. All are equal parts.

Central angle of a circle is 360 degree.

Since central angle divided into 10 equal parts, therefore central angle of each part is

`(360)/(10)=36`

From the figure it is noticed that f is on the third place of i in counterclockwise direction.

If we want to map i to f, the angle of rotation counterclockwise is

`3* 36^(\circ)=108^(\circ)`

Therefore have to rotate spinner 108 degree counterclockwise to label i to label f.
