What is polygon?
A polygon is a shape with three or more sides, in which each side touches another only at its endpoints. Some polygons that you are probably already familiar with are rectangles, squares, and triangles. Sum of Interior Angles of a Regular Polygon The sum of the interior angles of an n-sided regular polygon is n minus 2, times 1800 , where n represents a positive whole number.Sum of interior angles of a polygon = 180(n-2)Another way to remember the sum of the interior angles of a regular polygon is to cut the polygon into non-overlapping triangles by connecting vertices. Knowing that sum of the interior angles of a triangle is 1800 , multiply the number of triangles by 1800 to get the sum of the interior angles of the polygon. Example: Find the sum of the interior angles of a hexagon (6-sided polygon).
Again, the number of sides of a polygon is represented by n. In a hexagon, n = 6. Plug n into the formula:180(n-2) =180(6-2) = 180.4 = 720The sum of the interior angles of a hexagon is 7200

Solution by Factorization, please solve quadratic equations by Factorization.
Evaluate following limits. Solution Let's begin with the right-hand limit. For this limit we have, x > 4 ⇒ 4 - x 3 = 0 also, 4 - x → 0 as x → 4
A pool is surrounded through a deck that has the similar width all the way around. The total area of the deck only is 400 square feet. The dimensions of the pool are 18 feet throug
An irrigation system uses a straight 30m sprinkler pipe which is capped at one end and arranged so that all water is released directly downwards and pivots around a central point.
