Question

An ant, crazed by the Sun on a hot Texas afternoon, darts over an xy plane scratched in the dirt. The x and y components of four consecutive darts are the following, all in centimeters: (30.0, 49.0), (b_x, -68.0), (-17.0, c_y), (-85.0, -66.0).The overall displacement of the four darts has the xy components (-170, -28.0).What are (a) b_x and (b) c_y? What are the (c) magnitude and (d) angle (counterclockwise from the positive direction of the x axis) of the overall displacement?
