1) 20

2) 20

3) 12

4) 0.7

5)0.8

Step-by-step explanation:

when it asks questions like question 1 and 2 and 3 just take what the number is multiplied by

geometry: triangles

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
