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
Evgesh-ka [11]

Answer:

9

Step-by-step explanation:

Equation

Sum = s  = 180*(n - 2)

Solution

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

7 = n - 2                             Add 2 to both sides

9 = n            

Answer

The polygon has 9 sides.
