The hazell family has 4 children, murphy is 1 year younger than his older brother michael. keira is 2 years younger than murphy. isabella and keira are twins. if michael is 8, how old is izabella?

Micheal = M

murphy = M-1

Kiera = Murphy - 2 = (M-1) -2

Isabella = kiera = M-1-2

M=8

Isabella = 8-1-2

Isabella =5

idk

step-by-step explanation:

maybe try   if it is work from a book, if not try

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
