A coordinate plane has a horizontal x-axis labeled from negative 13 to 13 in increments of 13 and an unlabeled vertical y-axis. A line segment extends from the point (negative 13, 0) and rises from left to right to the point B on the positive y-axis. A line falls from left to right passing through the point B, the plotted point labeled P (x, ?), and the point labeled A at (13, 0). The rising line segment and the falling line intersect at a right angle at B. A vertical line segment extends from the positive x-axis to the plotted point P (x, ?). A horizontal line segment extends from the plotted point P (x, ?) to where it intersects the rising line segment. A vertical line segment extends from the negative x-axis to where the horizontal line segment intersects the rising line segment. The rectangle formed by the x-axis, the horizontal line segment, and the two vertical line segments is shaded.The accompanying figure shows a rectangle inscribed in an isosceles right triangle whose hypotenuse is
