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.
For a hexagon nut this angle may be shown to be one of 15Â°, as in Fig. 444. The darkest are sewed in the centre of each side of hexagon, with a white at each side, and two more (joined together) above it. The most common form of hexagon nut is shown in Fig. 405, the upper edge being chamfered off at an angle of about 40Â°.
