If my rent is $1895 and my roomate pays $795, what percent of the rent does she pay?

answer: he is 272195

step-by-step explanation: all you have to do is multiple 3535 and 77 and it equals 272195

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

yeah i know the problem you need. i am taking it right now. the answer is step 3
