You walk 55 m to the north, then turn 60° to your right and walk another 46 m. How far are you from where you originally started?
Can someone help me with this question please? I have tried Pythagorean but it did not work. thank

  • Physic -

    D = 55m@90o + 46m@30o,CCW from 0.

    X = 46*cos30 = 39.84 m..
    Y = 55 + 46*sin30 = 78 m.

    D^2 = (39.84)^2 + (78)^2 = 7671.2
    D = 87.6 m.
