Answer fast, please im in maths rn

Answer 1

`\sf x = 7.8`

Step-by-step explanation:

`\sf a^2 + b^2 = c^2`

`\hookrightarrow \sf 9.5^2 + x^2 = 12.3^2`

`\hookrightarrow \sf x^2 = 12.3^2 - 9.5^2`

`\sf \hookrightarrow x^2 = 151.29 - 90.25`

`\hookrightarrow \sf x^2 = 61.04`

`\hookrightarrow \sf x = √(61.04)`

`\hookrightarrow \sf x = 7.8`
