What dilation needs to be done to show that Circle D, with a center of (-3,6) and radius of 7, is similar to Circle E, with a center of (2,5) and a radius of 3?

i'm not entirely sure

step-by-step explanation:

if you ask home depot or lowe's they might be able to you out

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
