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 general formula for finding the number of triangles that can be formed is n-2, where ânâ is the number of sides of the polygon. The sum of the interior angles of a decagon is 1440 degrees, and the exterior angle of a decagon is 36 degrees. The interior angle of a decagon is 144 degrees.
