The sum of the interior angles, s, in an n-sided polygon can be determined using the formula s=180(n-2), where is thenumber of sides
using this formula, how many sides does a polygon have if the sum of the interior angles is 1,260? round to the nearest whole number
6 sides
7 sides
8 sides
9 sides

9 sides​

Step-by-step explanation:

Given formula to determine the sum of all interior angle of n-sided polygon,

Here, s =  1,260,

Hence, the polygon has 9 sides.

Last option is correct.

first anwser choice.

step-by-step explanation:

the greater/less or equal to symbol (> or < with the line at the bottom) is a closed/filled in circle.

-5c + 2 _< _27

subtract from both sides by 2

-5c _< _ 27

divide both sides by -5

c _< _ 5.4

flip the inequality sign

c _> _5.4

the only possible answer that would match the simplified inequality is the first answer choice
