Answer:
9 Sides
Step-by-step explanation:
According to the Question,
- Given That, The sum of the interior angles(s), in an n-sided polygon can be determined using the formula s=180(n−2), where n is the number of sides
Therefore, The sides do a polygon have if the sum of the interior angles is 1,260°.
Put The Values in Formula, we get
1260=180(n−2)
n-2 = 7
n=9 (9 Sides)
