<h3>
Answer: 1260 degrees</h3>
Explanation:
There are n = 9 sides to this polygon. Plug this value of n into the formula below to find the sum of the interior angles.
S = 180(n-2)
S = 180(9-2)
S = 180*7
S = 1260
Answer: the amount a person pays for gas compared with the number of gallons purchased
Step-by-step explanation:
Answer:
(x-5)^2 + (y+9)^2 = 144
Step-by-step explanation:
The equation of a circle can be written as
(x-h)^2 + (y-k)^2 = r^2
where (h,k) is the center and r is the radius
(x-5)^2 + (y- -9)^2 = 12^2
(x-5)^2 + (y+9)^2 = 12^2
(x-5)^2 + (y+9)^2 = 144
768.57 / 41.1 = 18.7 m per hr
