Answer:
6.9
Step-by-step explanation:
An octagon has 8 sides so:
55.2=8*x
x=55.2/8=6.9
It would be 20.15 because the 65% of 31 is 20.15
To solve for x, put all of the angle measurements on one side of an equation and set it equal to 360, because the sum of any exterior angles is 360 degrees. hope this helped!
