An ant travels in a perfectly straight line in the –x direction some distance. It turns, and then travels several new displacements, 30.0O above the +x axis, again, in a straight line, for some distance. The final leg of its little ant journey is a displacement of 15 cm, 40.0O below the +x axis, and its back at its starting point. What are the magnitudes of the first two displacements?
