TEOREMA DE PITÁGORAS
como determino o valor de X?​

Answer 1

14²=5²+x²

196=25+x²

196-25=x²

171=x²

$x = \sqrt{171} = 13.08 \: \: \: aproximadamente$

Answer 2

$\large \boxed{ \begin{array}{l} a {}^{2} = b {}^{2} + c {}^{2} \\ 14 {}^{2} = 5 {}^{2} + x {}^{2} \\ 196 = 25 + x {}^{2} \\ 196 - 25 = x {}^{2} \\ 171 \: = x {}^{2 } \\ x = \sqrt{171} \\ x = 3 \sqrt{19} \end{array}}$
