(1)  Make the sketch on your own.



(2)  From the given data, determine the length of the hypotenuse 


          XZ = sqrt%289%5E2+%2B+40%5E2%29 = sqrt%2881%2B1600%29 = sqrt%281681%29 = 41 cm.



(3)  Now complete the assignment on your own, using my instructions, given to you in my other response under this link
