M = negative 1 I hope this helps
The sum of all angles in a regular octagon is 1080 degrees. Because all sides are the same (regular octagon), all of the eight angles are the same too, so we simply divide 1080 by 8 and that is the solution.
1080/8 = 135
There is no TENTH in 192 so 192 rounded to the nearest TENTH is 192.
If you meant TEN then 192 rounded to the nearest TEN is 190.
Good Luck!
8,020 divided by 10 is 802.
Hope this helps!
