A pendulum hangs from a clock and swings over its base.
The distance between the pendulum and the base of the
clock, f(x), over the horizontal distance, x, is modeled by
the function shown.
f(x) = 0.25x² – 2x + 10
What is the minimum distance between the pendulum and
the base of the clock?

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
