Solve for x and y. In a right triangle, a perpendicular segment, labeled x, is drawn from the right angle to the hypotenuse. The segment of hypotenuse on one side of the perpendicular segment has length 7 and has length 5 on the other side. The side of the triangle adjacent to segment of length 7 has length y. y 5
