find the number of sides of a polygon which the sum of whose interior angle is 1440°
a.10
b.8
c.1
d.9​


Sagot :

ANSWER:

A. 10

EXPLANATION:

The sum of the measures of the interior angles of a decagon (10 sided polygon) is 1,440. We found this by using the formula (n-2)(180). Thus, to find the measure of each interior angle we simply divide the sum by the number of total sides in the polygon. 1,440/10 = 144.
