The formula is: (n-2)*180 = sum of interior angles
The internal angles of an n-sided shape add to (n-2)*180 degrees. So, for an 8-sided shape, they would add to 6*180 = 1080 degrees.
The equation to find the size of the interior angle of an n sided shape is (n-2)180/n For a 120 sided shape, you need to plug n=120 into this equation. (120-2)180/120 =118x180/120 =177 Thus a 120 sided shape does have an angle of 177 degrees, and the statement in the question is true.
Assuming it is regular, the total degrees of an n-sided polygon = 180(n-2) = 2700. 2700/17 = 158.23 degrees
The equation for and interior angle of an n sided shape is (n-2)180/n In this case we have a 12 sided shape. Plugging n=12 into the equation gives us: (12-2)180/12 = 10x180/12 = 150 Thus an interior angle of a 12 sided shape would be 150 degrees.
The sum of the interior angles of an icosagon is 3240 degrees, each angle of a regular icosagon being 162 degrees. * The formula for the sum of an n-sided polygon is 180 (n-2). 180 x 18 = 3240
(n-2)*180 3420 degrees
The sum of the interior angles of an n-sided polygon (I presume that's what you mean), in degrees, is 180 * (n - 2). Here, n is 9 so the answer is 7 * 180 which is 1,260 degrees.
The sum of the internal angles of a regular polygon with n sides is (n - 2) x 180 degrees. Therefore, the sum of the internal angles of a 14-sided shape (a tetrakaidecagon) is (14 - 2) x 180 = 2160 degrees.
A shape in 2D with n sides is called an n-gon. In higher dimensions, a shape with n sides is called an n-sided polyhedron.
(n - 2) times 180 degrees. Triangle: n=3, n-2=1 ===> 180 degrees Square: n=4, n-2=2 ===> 360 degrees etc.
A hexagon (six-sided figure) has a total of 720 degrees. The formula is: n = number of sides (n - 2) * 180
