This question cannot be answered fro a variety of reasons.
The polygon would have 10 sides.
A polygon with interior angle measures of 108 would be a pentagon
The only regular polygon with an interior angle of 90 degrees is the square, which has four sides. Other polygons can have an interior angle of 90 degrees, but they would not be regular polygons.
If each interior angle is 60 degrees then it will have 3 sides in the form of an equilateral triangle.
18 sides
The polygon would have 72 sides...
The polygon would have 10 sides.
That polygon would be a hexagon (6 sides).
It will have 26 sides

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.
If interior angle is 178o then the exterior angle = 180 - 178 = 2o So the number of sides = 360 / 2 = 180 sides.
Not possible - the smallest interior angle for a regular polygon is 60 degrees - which creates an equilateral triangle.
It would have 6 sides.
