A F-15 fighter plane is view from the ground; the angle enclosed by the length of plane is theta= 0.01744 radians at the point of observation. The Technical specifications of F-15 indicate that the length of the plane is 19.45 m. What is the height (r) of the plane from the ground?

In the figure we see that
r=2tan(θ/2)l=2tan[(0.01744⋅180/π)/2]19.45=1115 m.
