Answer:
C) 6 feet
Step-by-step explanation:
set up a proportion of height/shadow = height/shadow
30/10 = h/2
cross-multiply:
10h = 60
h = 6
If 2 lines (or line segments) are perpendicular, then the product of their slopes is equal to -1.
Thus, since the given line segments are perpendicular, we have:

.
Multiplying both sides of the equation by 15, we get d=-15.
Answer: d=-15
