easy, u have to do

10.2 cm - 5.9 cm

and that will equal 4.3

hope that helped! :]

[tex]\\ \sf\longmapsto ZY^2=XY^2-XZ^2[/tex]

[tex]\\ \sf\longmapsto ZY^2=10.2^2-5.9^2[/tex]

[tex]\\ \sf\longmapsto ZY^2=104.04-34.81[/tex]

[tex]\\ \sf\longmapsto ZY^2=69.23[/tex]

[tex]\\ \sf\longmapsto ZY=\sqrt{69.23}[/tex]

[tex]\\ \sf\longmapsto ZY=8.3cm[/tex]
