Every closed curve called a polygon can be separated into a specific number of triangles. Then, because the sum of the interior angles of a triangle is 180, you take the number of triangles and multiply by 180 to get the sum of the interior angles of the n-gon. To find the number of triangles that exist within an n-gon, subtract 2 from the number of sides. If our figure is a 17-sided polygon, then the number of triangles within it is 17 - 2 = 15. 15 triangles, each with a sum of 180 for its angles. 15 * 180 = 2700.
Each central angle is 360 divided by 17 to get 21°10'35"
Each interior angle is 2700 divided by 17 to get 158°49'24"
The interest charged on the principal for the entire loan term is known as Simple Interest. The interest computed on both principal and the previously earned interest is known as Compound Interest. Compound Interest gives a high return as compared to Simple Interest.
