Gestation or the length of pregnancy of a cat averages 64 days. It is generally between 62 and 67 days or about nine or ten weeks. When litters are large, length is often less. When litters are small, the length of the pregnancy may increase.
The sum of the interior angles of an octagon is 1080 degrees. In a regular octagon, divide by 8 for each angle = 135Â°. The formula for this is Sum = 180 (n-2) where n is the number of sides. (or 180n - 360) You can take the polygon and make [N] triangles, with points touching at the 'center'.
The sum of the degrees of any regular polygon with number of sides n is equal to (n - 2) x 180. Therefore, the sum of the internal angles in a decagon is equal to (10 - 2) x 1 â¦ 80 = 1440 degrees. + 10 others found this useful. Annika Segelhorst.
