Sudhir walk .40 km in a direction 60 degrees west of north then goes .50km due west. what is his displacement?

here the two displacements are given as

d1 = 0.40 km in direction 60 degree west of north

so here we will have

other displacement is given as

d2 = 0.50 km due west

total displacement is given as

so the magnitude of the displacement is given as

and its direction is given as

so displacement is 0.87 km towards 13.2 North of west

the answer is b
