A random sample of 35 four-door passenger vehicles had a mean gas mileage, in miles per gallon (mpg), of 25.9 mpg. The estimate had a margin of error of 2.6 mpg at a 98% confidence
level. Of the following, which is the most plausible value for the true mean gas mileage of all
four-door passenger vehicles?
А
24 mpg
В
29 mpg
С
32 mpg
D
35 mpg

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

180-142=38 for the acute angle next to the entry

90+38=128

180-128=52

a=52
