A goalie punts a soccer ball. If the ball is 1 foot above the ground when her foot meets the ball, find how long it will take, to the nearest hundredth of a second, for the ball to hit the ground. Use the formula h(t)=−16t^2+35t+h0 , where t is the time in seconds and h0 is the initial height. Please help this is really confusing to me

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

+2+=+%2836%2fx%29%5e2+

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
