Answer:

[tex]\sf x = 7.8[/tex]

explanation:

[tex]\sf a^2 + b^2 = c^2[/tex]

[tex]\hookrightarrow \sf 9.5^2 + x^2 = 12.3^2[/tex]

[tex]\hookrightarrow \sf x^2 = 12.3^2 - 9.5^2[/tex]

[tex]\sf \hookrightarrow x^2 = 151.29 - 90.25[/tex]

[tex]\hookrightarrow \sf x^2 = 61.04[/tex]

[tex]\hookrightarrow \sf x = \sqrt{61.04}[/tex]

[tex]\hookrightarrow \sf x = 7.8[/tex]
