U have to put a number between it
131,132,133,134,135,136,137,138,139
3000 + 70 + 2
It's basically everything that is added to get that number. You do not need a 100's place because a 0 is holding that spot.
A. it is a hexagon (there are 6 sides) B. using the equation (n-2)180 (where n is the number of sides we get (6-2)180=4*180=720. divide 720 by 6 to get 120 for each angle of the hexagon. (it has no irregularities in it's shape so that number will be correct for them all.) C. to get that just divide 39 by 6 to get 6.5 in per side. Hope that helps:)
