Mr. Wells drew a plan for a rectangular dog run. The vertices are
(23, 72). (12,72), (12, 1), and (2, 1). What
is the perimeter of the dog run?

the two may have that, even a breakdown is probably offered

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

there are no answer choices
