Equation A works when you plug the values in
So, I think Choice A is right
|x + 11| = 8
x + 11 = 8
<u> -11 -11</u>
x = -3
|3x - 2| = 16
3x + 2 = 16
<u> -2 -2</u>
<u>3x</u> = <u>14</u>
3 3
x = 4 2/3
14.4166667 feet (14 feet 5 inches)
This is the formula:
Arc length = 2(3.14)(3)(60/360)
18.84(60/360)
18.84 x 0.16 = 3
The length of the arc = 3
