Mahala is standing and fishing on a dock that is 2 1/4 feet above the surface of the water in the pond. her baited hook is 1.5 feet below the surface of the water. the surface of the water is represented by the rational number 0. use the number line to graph the distance the dock, point d, is above the water and the hook, point h, is below the water. make sure you label each point appropriately.

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
