The formula for the sum of the interior angles for a polygon having n sides = 2n - 4 right angles. 3240 ÷ 90 = 36 right angles : When 2n - 4 = 36 then 2n = 36 + 4 = 40 : n = 20 The regular polygon has 20 sides.
7 sides, which makes it a heptagon. A polygon is any shape with 3 or more sides.
20 sides The relationship between the sum of interior angles and number of sides is (Sum of angles)/180° + 2 3240/180 + 2 = 18 + 2 = 20 This kind of figure is called an icosagon. 20 sides Alternatively you can find it from the formula Sum of the angles of an n-sided polygon = 180(n-2). So solve the following for n: 3240= 180(n-2) n-2=3240/180=18 n=18+2=20
Providing that it's a regular polygon then: 360/15 = 24 sides
It will have 360 sides.
20 sides
n = (3240 + 360)/180 ie 20
20
The sum of the interior angles of a polygon with n sides is (n-2)*180 degrees So (n-2)*180 = 3240 Hence n-2 = 18 so that n = 20.
The formula for the sum of the interior angles for a polygon having n sides = 2n - 4 right angles. 3240 ÷ 90 = 36 right angles : When 2n - 4 = 36 then 2n = 36 + 4 = 40 : n = 20 The regular polygon has 20 sides.
7 sides
8 sides
11 sides
7 sides, which makes it a heptagon. A polygon is any shape with 3 or more sides.
18 Angles on a straight line = 180 degrees interior angles 2880 + exterior angles 360 = 3240 degrees 3240 divided by 180 = 18 sides Note that the exterior sum of angles of any polygon is always 360 degrees.
