A person moves towards north a distance 20m from point P and reaches at Q. He turns 135 degrees in clockwise direction and goes 40√2m. From here he turns 135 degrees clockwise and goes 25m. How far is he now from his initial position?
(If you could, could you explain with a rough illustration or something-for better understanding?)
sorry, bud -- no illustrations here.
P is at (0,0) PQ heading is N
Q is at (0,20) QR heaing is SE
R is at (40,-20) RS heading is W
S is at (15,-20)
PS is thus 25
A PERSON MOVES TOWARDS NORTH A DISTANCE OF 25 M FROM A POINT P AND REACHES AT Q. HE TURNS 135 DEGREE CLOCKWISE AND GOES 25*UNDERROOT 2 (i.e. root 2) M . FROM HERE HE TURNS 135 DEGREE CLOCKWISE AND GOES 20 M
