1) graphs y = -9x + 12 and y = 1/3x - 12 are not coincident.
2) The graphs are not parallel, because the angular coefficients are not equal
3) The condition of perpendicularity:
, where 
- not perpendicular
find the area first then add 22 and 5
Answer:

25^2=15^2+x^2 where x=tree height less the 2' from the top
x=20'
Add the 2' from wire connection to top of tree.
