Question

What is the angle of rotation counterclockwise about the spinner’s center that maps label g to label B?

A). 144°
B). 216°
C). 180°
D). 108°

Answer 1

well from angle g to angle B is a straight line. All straight lines have a degree of 180

Answer 2

The angle of rotation counterclockwise about the spinner’s center that maps label g to label B is:

Option: C (C) 180°)

Explanation:

We know that a angle formed by a straight line is always of the measure 180 degree i.e. 180°.

Clearly by looking at the spinner we see that the in order to map label g to label B we have to set the needle of the spinner straight and hence the angle so formed by the needle of the spinner is: 180 degree (180°).

Option: C is the correct answer.

C) 180°
