Can you use the digits from 1-9 and the four operations (+, -, %, x) to make a 100 (or as close as possible). You can only use each digit once, but you can use each operation as many times as you’d like. You may also combine numbers to make larger numbers. For example 3 and 9 to make 39.

46.2+112.3

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
