a. 31
b. 3 and 4
c. 1

31

Step-by-step explanation:

the mode is the number that appears the most, in that case it would be 31. i also just did this in a quiz 2 seconds ago and was right.

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+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
