A 10 sided decagon has interior angles that add up to 1440 degrees
The sum of the interior angles of a polygon with n sides is 180*(n-2) degrees.
The polygon would have 10 sides.
(number of sides -2)*180 = sum of interior angles
No, a convex polygon cannot have an interior angle sum of 400 degrees. The sum of the interior angles of a convex polygon is always equal to (n-2) * 180 degrees, where n is the number of sides. Since the sum of the interior angles must be greater than 180 degrees for each interior angle, a convex polygon with an interior angle sum of 400 degrees would require at least 9 sides, which would make it a nonagon, not a polygon.
24 sides

There is no regular polygon with an interior angle of 20o. If the interior angle is 120o then there are six sides and the sum of the angles is 720o.
The answer is 11 sides If a polygon with 10 sides the sum of the interior angles are 1440° So 1440°+180°= 1620°
360 degrees
It will have 26 sides
