Answer:
5
Step-by-step explanation:
Hello There!
The mean is pretty much the average
So to find the mean we first add up all of the values
2+3+6+6+7+8+8=40
Then we count the amount of points
There are 8 points
our final step is to divide the total value by the total number of points
40/8=5
so the mean (average) would be 5
The sum of a polygon's angles are 540.
When you add all the angles together here, you get 456.
Now subtract 456 from 540.
540 - 456 = 84
