Roberto, Mikayla, and Ariel are sharing a pie. Roberto cuts the pie into different size slices. Ariel takes a slice that is 2 pi over 3 radians. Roberto takes a slice is smaller than Ariel's
slice and Mikayla takes a slice that is larger than Ariel's slice. What are possible measures,
in radians, of Roberto's slice and Mikayla's slice of pie?
Hint: There is only one pie for all 3 people. One pie has a total measure of 2 pi radians.
