Given : joy walked 35m toward south then he turned to his left and walked 25m he turned to his left and walked 35m he again turned to his right and walked 10m and then turned left and walked 12m at
To Find : what distance is he from the starting point and in which direction
Solution:
NORTH
WEST EAST
SOUTH
Walked SOUTH = 35 m = -35 m NORTH
Left from South = EAST = 25 m
Left from East = NORTH 35 m
Right From North = EAST 10 m
Left from East = NORTH = 12 m
Total EAST = 25 + 10 = 35 m
Total NORTH = -35 + 35 + 12 = 12 m
Distance from Starting point = √12² + 35² = √37² = 37 m
He is at 37 from Starting point
Direction is North East
= tan⁻¹(12/35) = 18.92° North from East
