Question:

In Figure, a radar station detects an airplane approaching directly from the east. At first observation, the airplane is at distance d1 = 360 m from the station and at angle θ1 = 40o above the horizon. The airplane is tracked through an angular change ??θ = 123o in the vertical east-west plane; its distance is then d2 = 790 m. Find the

(a) Magnitude and

(b) Direction of the airplane's displacement during this period.
