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'.
A polygon will always have the same number angles as sides. So a decagon has 10 angles. The sum of measures of interior angles (inside the angles) of a polygon is 180 * (n - 2) where n is the number of angles in the polygon. For a decagon, it would be 1440 degrees. To find the measure of one interior angle of a congruent polygon, (all sides are equal and all angles are equal), divide by n. This gives you 144 degrees for a congruent decagon. 285 Views Â· View Upvoters
