The height of a snowball thrown off a 128-foot cliff is modeled by the function h(t) = −16t2 + 64t + 192, where h is height in feet and t is time in seconds. Find the time the snowball takes to reach the ground. PLEASE HELP

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
