Answer 2

*See attached diagram

Find the distance of point P to the foot of the building:

tan θ = opp/adj

tan (30) = 10/distance

distance = 10/tan(30)

Find the height of the helicopter:

tan θ = opp/adj

tan (60) = height ÷ 10/tan(30)

height = 10/tan(30) x  tan(60)

height = 30 m

Answer: The helicopter is 30 m above ground
