Answer fast, please im in maths rn

Answer 1

Answer:

$\sf x = 7.8$

explanation:

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

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

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

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

$\hookrightarrow \sf x^2 = 61.04$

$\hookrightarrow \sf x = \sqrt{61.04}$

$\hookrightarrow \sf x = 7.8$
