Solve the problem.A woman walks 100 yards eastward along a straight shoreline and then swims 30 yards southward into the ocean on a line that is perpendicular to the shoreline. Using her starting point as the pole and the east direction as the polar axis, give her current position (i) in rectangular coordinates and (ii) in polar coordinates. Round the coordinates to the nearest hundredth. Express ? in degrees.
A. (i) (-100, 30); (ii) (104.40, -88.28°) B. (i) (100, -30); (ii) (11.40, -88.28°) C. (i) (100, 30); (ii) (11.40, -16.70°) D. (i) (100, -30); (ii) (104.40, -16.70°)
