Honestly, you sound like a psycho but you should try talking to someone face to face to see what's wrong with you and it doesn't have to be your parents.

May be your sadistic, the part where you said you wanted to laugh when that was happening to your sister. It doesn't sound like a normal sadistic tendency but a kinda low one.

factor trees are nice.

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
