The triangle that is formed from by connecting the shadow, the tree and the endpoints of each is a right triangle. The two triangles formed (by the tree and its shadow, and by Rachel and her shadow) are similar. In similar triangles, the corresponding sides are proportional. Thus, to give the numerical answer to this item,
length of the tree/14 ft = 6 ft / 3.5 ft
length of the tree = 24 ft
(x+4)+135.8=180.0
-135.8.-135.8
x+4= 44.2
-4 -4
x= 40.2
X=8/7 decimal form: 1.142857 mixed number form: 1 1/7
Y=-4x+28

y=-4x-12
y=-4x-4
y=mx+b
m=slope
b= y intercept
C is the answer
The answer is to that question is 9.
