Answer 1

Respuesta:

 [tex]x =96cm, y = 50cm ;[/tex]  la correcta es la opción    a )

Explicación paso a paso:

Por Pitágoras:

[tex]x^{2} = (104cm)^{2} -(40cm)^{2}[/tex]

[tex]x^{2} = 10816cm^{2} -1600cm^{2} = 9216cm^{2}[/tex]

[tex]x = \sqrt{9216cm^{2} }[/tex]

[tex]x = 96cm[/tex]

[tex]y^{2} = (40cm)^{2} +(126cm-96cm)^{2} = (40cm)^{2} +(30cm)^{2} = 1600cm^{2} +900cm^{2}[/tex]

[tex]y^{2} = 2500cm^{2}[/tex]

[tex]y = \sqrt{2500cm^{2} }[/tex]

[tex]y = 50cm[/tex]
