Answer:
40 degrees.
Step-by-step explanation:
A circle has a total of 360 degrees.
If a third of the circle remains, it will have one third that amount.
360 / 3 = 120
So 120 degrees remain.
If the remaining amount is cut into three slices, each slice will be one third of that amount.
120 / 3 = 40
Each slice has an angle measure of 40 degrees.
