Suppose a robot's arm can change its length in addition to rotating about the origin in a coordinate plane.

Suppose a robot's arm can change its length in addition to rotating about the origin in a coordinate plane. If the hand is initially at (12, 17), approximately how many degrees should the arm be rotated and how much should its length be changed to move the hand to (−16, 18)? (Round your answers to the nearest 1° and 0.1 inch.)
