He 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. benita solves this equation for n and writes the equivalent equation n = + 2. using this formula, how many sides does a polygon have if the sum of the interior angles is 1,260°?

9

Step-by-step explanation:

Equation

Sum = s  = 180*(n - 2)

Solution

1260 = 180*(n - 2)             Divide by 180

1260 / 180 = 180 * (n -2 ) / 180

7 = n - 2                             Add 2 to both sides

9 = n            

Answer

The polygon has 9 sides.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
