The sum of angles in a regular n sided polygon:
(n - 2)*180
(n - 2)*180 = 11520
(n - 2) = 11520/180
(n - 2) = 64
n - 2 = 64
n = 64 + 2
n = 66
Polygon has 66 sides.
Answer:
The equation is 18h=378
h=21
Step-by-step explanation:
So first you have to set up the equation
so if she makes 18 dollars an hour the first part of the equation would be 18h
She made 378 dollars in one week so now the equation is 18h=378
The answer is h=21 because 378/18 is 21
After solving for w using inverse operations, w would have to equal 5.74 to make this equation true.
