Starting from point O, a boat sails successively along three displacement vectors:
(i) 8km due east,
(ii) 5km at 30∘ north of east,
(iii) 6km due north.
(a) Find the magnitude of the resultant displacement from O.
(b) Determine the angle this resultant makes with the east direction, correct to the nearest degree.
