    Compute the north and east displacements of both legs of the journey.

    Add the two north displacements. Call that sum Y

    Y = 810 cos75 + 648 cos32 = __

    Add the two east displacements. Call that sum X.

    X = 810 sin75 + 648 sin32 = ___

    Straight-line distance = sqrt[X^2 + Y^2]
