Question

there are 3 slices of pie left, and the angle measurement is 72 degrees, how many slices was the pie cut in to

Answer 1

15; this is because 3 pies make up 72
with this you can make it so that 3x=72 
After this you need to find x which is a single pie
so; (3x/3)=(72/3)
      x= 24
Since you know a circle is 360 degrees all around the center
You can do 360/24 making it 15 pies.
