Question

urgente, com o cálculo

calcule o valor de X

Answer 1

x = 4

Teorema de Pitágoras:

cateto² + cateto² = hipotenusa²

x² + 3² = 5²

x² + 9 = 25

x² = 16

x = √16

x = 4.

Answer 2

$\large{\begin{array}{l} \rm x {}^{2} + 3 {}^{2} = 5 {}^{2} \\ \rm x {}^{2} + 9 = 25 \\ \rm x {}^{2} = 25 - 9 \\ \rm x {}^{2} = 16 \\ \rm x = \sqrt{16} \\ \rm x = 4 \end{array}}$
