A famous data set was collected in Scotland in the mid-1800s. It contains the chest sizes, measured in inches, of 5738 men in the Scottish Militia.
Estimate the percent of the chest sizes that lie within (a) 1 standard deviation of the
mean, (b) 2 standard deviations of the mean, and (c) 3 standard deviations of the mean.
Explain your reasoning.

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
