Question

Calcula “x “.
a)1
b)2
c)1/2
d)3
e)1/3

Answer 1

Respuesta:

$J=\frac{40^{g} }{\frac{\pi }{10}rad}$

convertimos $\pi /4$ a grados centesimales

$\frac{R}{\pi } =\frac{C}{200}\\\frac{\frac{\pi }{10} }{\pi } =\frac{C}{200}\\\frac{1}{10} =\frac{C}{200}\\\\C=\frac{200}{10} \\C=20^{g}$

reemplazamos en J

$J=\frac{40^{g} }{20^{g} } \\J=2$
