A decagon
Exterior angles: 360 Interior angles: 1440
A 10 sided decagon polygon has 10 interior angles that add up to 1440 degrees.
It will have (1440+360)/180 = 10 sides which is a decagon
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. 1440 degrees
The answer is 11 sides If a polygon with 10 sides the sum of the interior angles are 1440° So 1440°+180°= 1620°
The interior angles of a 10 sided polygon add up to 1440 degrees
A decagon
A 10 sided polygon or a decagon has interior angles that add up to 1440 degrees
1440 degrees. The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees.
The sum of the interior angles of any regular polygon of n sides is equal to 180(n - 2) degrees. In this instance, the sum of the interior angles of a decagon is equal to 180 x (10 - 2) = 1440 degrees.(10-2)*180 = 8*180 = 1440 degrees.
Exterior angles: 360 Interior angles: 1440
A polygon with 10 sides is called decagon and the sum of the interior angles is 1440 degrees. (10-2)180=1440
A 10 sided decagon polygon has 10 interior angles that add up to 1440 degrees.
A 10 sided decagon polygon has 10 interior angles that add up to 1440 degrees.
If it has n sides, then (n-2)*180 = 1440 so n-2 = 1440/180 = 8 and therefore, n = 10 It is a decagon.
A decagon, with ten sides. The formula for sum of the interior angles of a polygon is 180(n-2), where n is the number of sides. From the problem statement, 1440 = 180n - 360, or n = 10.
