call the larger triangle abc
then the smaller triangle cde is similar to abc (all angles are equal, aaa).
ab is the side that is 36, and we wish to find de, the side corresponding to ab
area_cde = area_abc - area_cde --> area_abc / area_cde = 2
let x=length of de
ratio of areas = (ratio of sides)^2
step-by-step explanation:these are your clues: 1. kim ran 18 races2. this was four fewer races than twice thenumber, notice it says twice the number, so you would do the equation 18x2-4; which equals the number 32.thus, 32 is your answer.
they have to be opposite and reciprocal of eachother.
