Question

An aircraft flying onto an airport calls out the control tower and says it is at height of 500m above the tower. If its horizontal distance from the tower is 8km, calculate the angle of elevation from the tops of the tower.

Answer 1

1km = 1000m
8km = ?
       =8000m
tanθ = 500 
           8000
tanθ = 5 
           80
tanθ = 0.0625
    θ =3.58
