Answer:
d ≈ 1732 ft
Step-by-step explanation:
Angle of elevation = Angle of depression
Following this truth,
m∠PAQ (Angle of depression) = m∠APB (Angle of elevation) = 30°
By applying tangent rule in the given triangle ABP,
tan(30°) =
d = 1000√3
d = 1732.05
d ≈ 1732 ft

Add the equations together:
12x-12x-11y-5y=40+88
you get
-16y=128
divide y=128/-16
y=-8
then plug-8 for y back into either equation.
12x-11(-8)=88
12x+88=88
12x=0
x=0
