Answer:

x = 8

Step-by-step explanation:

[tex]a^{2} +b^{2} =c^{2} \\[/tex] so [tex]8^{2} +b^{2} =\sqrt{80} ^{2}[/tex]

rearrange the formula:

[tex]\sqrt{80} ^{2} - 8^{2} = b^{2}[/tex]

[tex]80 - 64 = b^2[/tex]

[tex]b^2 = 16\\[/tex][tex]b = \sqrt{16}[/tex]

[tex]\sqrt{16} = 4[/tex]

[tex]x = 4+4 = 8[/tex]
