US workers earning $75,000 or more who did not own vehicles had seven commuting choices normally distributed with a population standard deviation of 61.4 people and an unknown population mean. If a random sample of 410 workers is taken and results in a sample mean of 58.6 square feet, find the error bound (EBM) of the confidence interval with a 90% confidence level.

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
