Answer:
70 degrees
Step-by-step explanation:
Angle BZA = Angle BZC = 20 degrees
Reason : These two angles are Vertically opposite angles.
Angle BZA + Angle BZC = 90
20 + Angle BZC = 90
Angle BZC = 90 - 20
Angle BZC = 70 degrees
Is 20 and answer because I did this on a calculator and this is the only one to me that would make since
I would say A because you would expect that less than half of them are out of state as more then half in the study are in state.
