If the distance between location A to B is straight east 10 km. then from B to C is Nw 18KM How far would you be from point C to A.

Would you not need to more information then this to calculate this answer?

  • math -

    Use the Pythagorean Theorem.

    (AB)^2 + (AC) ^2 = (BC)^2

    substitute for AB and BC.
    then solve for AC

  • math -

    no, just use the cosine law
    AC^2 = 10^2 + 18^2 - 2(10)(18)cos45° ---- assuming that Nw meant "northwest"

    = 169.44...
    AC = √169.44.. = appr 13.02 km

  • math -

    Sorry, I got in a hurry.
