Bill is riding on a Ferris wheel with radius of
27 ft that is turning
counterclockwise at a rate
of one revolution every 15
seconds. Assume the lowest
point of the Ferris wheel (6
o'clock) is 8 ft above the
ground, and that Bill is at
the point marked A(3 o'clock)
at time t=0. Find his
position after 10 seconds
into the ride.

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
