Max observes the zoo and the library from a helicopter flying at a height of 400 times square root of 3 feet above the ground, a
-BARSIC- [3]

Answer: First option: 800 feet

Solution:

Height: h=400 sqrt(3)

Distance between the zoo and the point in the ground below the helicopter: d1=?

Distance between the library and the point in the ground below the helicopter: d2=?

Distance between the zoo and the library: d=?

d=d2-d1


tan 60°= h/d1

sqrt(3)=400 sqrt(3) / d1

Solving for d1:

sqrt(3) d1 = 400 sqrt(3)

d1= 400 sqrt(3) / sqrt(3)

d1=400


tan 30°= h/d2

sqrt(3) / 3=400 sqrt(3) / d2

Solving for d2: Cross multiplication:

sqrt(3) d2 = 3 [ 400 sqrt(3) ]

sqrt(3) d2 = 1,200 sqrt(3)

d2= 1,200 sqrt(3) / sqrt(3)

d2=1,200


d=d2-d1

d=1,200 feet - 400 feet

d=800 feet
