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+

you can not solvr this without numbers

the solution, from the graphing of the two lines, is (3,2), i.e., x = 3, y = 2.

we would need a picture of the quadrilateral in order to answer the question. also, it seems that the question is missing some components.
