Hello from MrBillDoesMath!
Answer:
283 degrees
Discussion:
A circle has 360 diverges so summing up all the angles gives:
360 = (7y - 7) + (20y-11) + (4y + 6) => combine like terms
360 = (7y + 20y + 4y) + (-7 - 11 + 6) =>
360 = 31y - 12 => add 12 to both sides
372 = 31y =>
y = 372/31 = 12
measure arc ABC =
360 - measure arc (7y-7) =
360 - (7*12-7) =
360 - (77) = 283
Thank you,

The area of the outer circle
Answer:
B. 4.5 mi.
Step-by-step explanation:
Let g = length of green route
b = length of blue route
(1) 6g + 5b = 52 (2) 12g + 13b = 119
Mult. (1) by -2 <u> -12g - 10b = -104</u>
<u> </u> 3b = 15
b = 5
6g + 5(5) = 52
6g + 25 = 52
6g = 27
g = 27/6 = 9/2
