Respuesta:
R= 90 ..... clave E
Explicación paso a paso:
*Tenemos:
[tex]\frac{S}{C} + \frac{C}{S} = \frac{181}{R} \\[/tex]
*Reemplazamos:
[tex]S = \frac{180 R}{\pi} \\C= \frac{200 R}{\pi}[/tex]
[tex]\frac{\frac{180 R}{\pi} }{\frac{200 R}{\pi} } + \frac{\frac{200 R}{\pi} }{\frac{180 R}{\pi} } = \frac{181}{R}[/tex]
[tex]\frac{9}{10} + \frac{10}{9} = \frac{181}{R} \\\frac{181}{90} = \frac{181}{R} \\R= 90[/tex]
