Sam cut a pie into equal slices. There are only 3 slices left. The angle measure of the 3 slices is 72 degrees How many slices did sam cut the pie into?

Find out how many degrees is in each slice.
Divide that answer into 360 which is the number of degrees in the circle and then you will find the number of slices.
You could set up a proportion:
72/3 = 360/? 
72/3=24
24 degrees is one slice of pizza
24x=360
x=360/24
x=15
15 slices 
24
