If A B and C are the alternatives, the answer is B: 12.9
The reason is that the hypotenuse can't be smaller than one of its sides, that eliminates alternative C.
And also, the hypotenuse can't be bigger than segments AC + BC, since the side AC is bigger and AC measures 10.8, the hypotenuse would have to measure < 21.6
this is because you divide the total wage by how many hours each person works for, ian earns 13 dollars an hour, Cody earns 11 dollars an hour, and Cindy ears 12 dollars and 50 cents per hour.
