    split into right angled triangles xz=yw so you have one side 15 and one side 8 you want to work out the hypotonuse a²+b²=c² 8²+15²=289 square root 289 to get c c=17

    use pythagoras theorem since opposite sides of a rectangle are equal base=15 inches and altitude=8 inches Applying pythagoras theorem \[15^{2}+8^{2} =h^{2} \] \[\sqrt{289}\] =17 therefore length of diagonal is 17
