HELP ME PLEASE 8. Consider the chord obtained by taking the seventh chord and flatting
its fifth. Such a chord is sometimes labeled with the suffix 7-5. Show
that this chord does not have a discernable root. Write an example of
such a chord and give all possible labelings of iT.
Thank you

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+
