A sailboat racecourse consists of four legs, defined by thedisplacement vectors 𝐴𝐴���⃗, 𝐵𝐵���⃗, 𝐶𝐶���⃗, and � 𝐷𝐷��⃗, as thedrawing indicates. The magnitudes of the first three vectors are A= 3.20 km, B = 5.10 km, and C = 4.80 km. The finish line of thecourse coincides with the starting line. Using the data in thedrawing, find the distance of the fourth leg and the angle θ
