E = mc2
The energy for a fusion reaction does not.
B. More energy is produced per reaction in a fusion reaction than in a
fuel cell.
C. Fusion reactions produce more energy because they use more
hydrogen than fuel cells do.
D. The energy produced from a single atom of hydrogen in a fuel cell
is the same as the energy produced from a single atom of
hydrogen in a fusion reaction.

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
