It is approximately 128.57
An irregular septagon: the right-angle will prevent it being regular.
Each interior angle of a regular 7 sided polygon is 128 degrees 34 minutes and 17.14 seconds
It's 900 degrees, and it doesn't matter whether the 7-sided polygon is regular or not.
Any 7-sided polygon will do that for you.
Providing that it is a regular 7 sided polygon then each interior angle is 900/7 degrees
the interior angle of a 7 sided regular polygon is 128.57 degrees
It is approximately 128.57
a 7 sided polygon is heptagon and the interior angle of it is 128.57 degrees.
The equation for the size of an interior angle of an n-sided regular polygon is (n-2)180/n. When n=7, the interior angle of a regular sided shape would be 5x180/7 or approximately 128.57. The polygon in the question has an interior right angle (90 degree angle) and thus cannot be a regular shape. A 7 sided shape is called a heptagon. Thus, the shape described in the question is an irregular heptagon.
An irregular septagon: the right-angle will prevent it being regular.
Each interior angle of a regular 7 sided polygon is 128 degrees 34 minutes and 17.14 seconds
The interior angles of a 7 sided polygon add up to 900 degrees
Not to 1000 degrees but a 7 sided polygon's interior angles add up to 900 degrees
The heptagon (7 sided polygon) cannot tessellate. The exterior angle of the heptagon is 51.43 degrees which makes the interior angle 128.57 degrees.
To answer this question it has to be assumed that it is a regular polygon ie with equal angles. Sum of the interior angles = (7-2)*180 = 5*180 = 900 degrees So each interior angle = 900/7 = 128.57 degrees.
It's 900 degrees, and it doesn't matter whether the 7-sided polygon is regular or not.
