Answer 1

Respuesta:

 $x =96cm, y = 50cm ;$  la correcta es la opción    a )

Explicación paso a paso:

Por Pitágoras:

$x^{2} = (104cm)^{2} -(40cm)^{2}$

$x^{2} = 10816cm^{2} -1600cm^{2} = 9216cm^{2}$

$x = \sqrt{9216cm^{2} }$

$x = 96cm$

$y^{2} = (40cm)^{2} +(126cm-96cm)^{2} = (40cm)^{2} +(30cm)^{2} = 1600cm^{2} +900cm^{2}$

$y^{2} = 2500cm^{2}$

$y = \sqrt{2500cm^{2} }$

$y = 50cm$
