If you have a Lease, you should look to when the month-to-month obligations are effective. If it states that you pay on a calendar month basis, then your notice will be considered as being more that the required 30 days, and that you owe for the full following month.
A regular polygon is equiangular, which means all angles are the same measure. In the case of a regular hexagon, the sum of 720 degrees would be distributed evenly among the six sides. So, 720/6 = 120. There are six angles in a regular hexagon, each measuring 120 degrees.
A hexagon has six sides, and the sum of interior angles of a polygon can be calculated in the formula: #180(n - 2)#, where #n# is the number of sides in the polygon. Since a hexagon has six sides, the sum of interior angles is #180(6-2)=180(4)=720#, so the angle of each side of a hexagon is #720/6=120#. Thus, a hexagon has zero right angles.
