Answer:
10 sides.
Step-by-step explanation:
As we know sum of the measures of the interior angles of any polygon is represents by (x-2)180°
Therefore, total sum of interior angles = (x-2)×180°
where x is the number of sides of a particular polygon.
It is given that sum of interior angles = 1440°
1440 = (x-2) × 180°
[tex]\frac{1440}{180}[/tex] = (x-2)
8 = (x-2)
x = ( 8+2) = 10
Therefore, polygon have 10 sides.
