Arrange the following numbers in descending order.

123.75, 127.53, 125.37, 231.75

A
231.75, 127.53, 123.75, 125.37

B
231.75, 123.75, 127.53, 125.37

C
231.75, 127.53, 125.37, 123.75

D
127.53, 125.37, 123.75, 231.75

the 3rd option is right

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

b. hoped i'm right lol
