Lucy made tables of values to approximate the solution to a system of equations. First she found that the x-value of the solution was between 1 and
2, and then she found that it was between 1.5 and 2. Next, she made this
table.

Which ordered pair is the best approximation of the exact solution?
A. (1.6, 1.3)
B. (1.9, 1.5)

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+
