Ayudaaaaaa porfa doy corazon y corona

Answer 1

Explicación paso a paso:

$a {}^{2} + {b}^{2} = {c}^{2} \\ {6}^{2} + {6}^{2} = ((x - 1) \times \sqrt{2} ) ^{2} \\ 36 + 36 =( x {}^{2} - {1}^{2} ) \times 2 \\ 72 =( {x}^{2} - 1) \times 2 \\ \frac{72}{2} = {x }^{2} - 1 \\ 36 = {x}^{2} - 1 \\ \sqrt{36} = \sqrt{ {x}^{2} - 1} \\ 6 = x - 1 \\ x = 6 + 1 = 7$

espero haberte ayudado
