Maria cut a pizza into 8 equal slices. she put a slice of pizza on 3 plates. what is the measure of the angle for the slices that are left

A circle has a total number of 360 degrees, so you would divide 360 by 8, and that would tell you how many degrees each slice is (40). After that, you would subtract 3 from 8 to show that there are 5 pieces left, which you would then multiply by 40 because each slice is 40 degrees, so you would get an answer of 200 degrees.
