A quarterback takes the ball from the line of scrimmage, runs backwards for 12.0 yards, and then runs sideways parallel to the line of scrimmage for 12.5 yards. At this point, he throws a 52.0-yard forward pass straight downfield, perpendicular to the line of scrimmage. How far (in yards) is the football from its original location?
