Answer 1

Answer:

72°

Option D is correct

Explanation:

Sum of angles in a circle = 360°

Carol budgets 20% of her income for food.

This means that Carol will use 20% of the 360° in the circle to show this item

The measure of the central angle she must use to show this item on a circle graph = (20/100) x 360°

The measure of the central angle she must use to show this item on a circle graph = 72°
