A pie graph represents the whole data as 360 degrees. So if pepperoni pizza is 24/72 of the distribution, it would be represented by 1/3 of the graph which is (1/3)(360°) = 120°. Therefore, the answer is B. A pie graph represents the total distribution as a circle of 360°. To find the angle needed to represent a specific part of the distribution, we need to calculate its fraction of the total and multiply it by 360°.

If pepperoni pizza is 24/72 of the distribution, then its fraction is:

24/72 = 1/3

To find the angle needed to represent 1/3 of the circle, we multiply by 360°:

1/3 × 360° = 120°

Therefore, the answer is B) 120°.
