You can find out where the majority of the Register families were living before they immigrated to the U.S and learn where to focus your search for foreign records. Immigration records can tell you an ancestor's name, ship name, port of departure, port of arrival, and destination.
So the general rule is: Sum of Interior Angles = (n -2) Ã 180 Â°. Each Angle (of a Regular Polygon) = (n -2) Ã 180 Â° / n. Perhaps an example will help:
These are the correct answers to the following questions: (1) b. 3,240o. The sum of the interior angle measures of a 20-gon is 3,240o.. (2) d. 150o. The measure of one interior angle of a regular 12-gon is 150o.. (3) a. 40. The value of x in the regular polygon below is 40.. (4) d.45o.
