[tex]Pitagoras: x^{2} +y^{2} =z^{2} [/tex]
[tex]4^{2} +7^{2} =x^{2} \\
16+49 =x^{2}\\
65 = x^{2} \\
x=\sqrt{65} [/tex]
[tex]y^{2} +4^{2} =(4\sqrt{10} )^{2} \\
y^{2} + 16 = 16 * 10\\
y^{2} + 16 = 160\\
y^{2} =144\\
y = \sqrt{144} \\
y=12[/tex]
[tex]4^{2} +z^{2} =9^{2} \\
16 +z^{2} =81 \\
z^{2} =65\\
z=\sqrt{65} \\[/tex]
