The pressure of earths atmosphere at sea level is approximately 1000 millibars, and it decreases by a factor of 2 every 7 km as you go up in altitude.
a) if you live at an elevation of 1 km (3300 ft) what is the atmospheric pressure?
b) what is the atmospheric pressure at the top of a mountain that is 7722 meters?
c) by approximately what percentage does atmospheric pressure increase every km?

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
