Can someone please help me with this question!

A

Step-by-step explanation:

The x value of the center = 0

The y value of the center = 220/2 + 11 = 110 + 11 = 121

so the center is at (0,121)

The radius is 220/2 = 110

The equation of the Ferris Wheel is

x^2 + (y - 121)^2 = 110^2

x^2 + (y - 121)^2 = 12100

step-by-step explanation:

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
