Angelo is riding in a hot air balloon. the balloon begins at 700 feet
above the ground. it drops 200 feet, rises 500 feet, and then drops
100 feet. write and evaluate an expression to find angelo's position
relative to the ground.

700-200+500-100=900

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
