answer: d. $20
just took the test
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
a) the midrange of the data set shown is 85.5
step by step explanation
let's find the midrange.
the midrange is nothing but add the greatest value and the least value, then divide it by 2.
here the greatest value = 99
the least value = 72
midrange = (99 + 72)/2
midrange = 85.5
