Explicación paso a paso:
Sistema de medición angular son tres
Sexagesimal (S)
[tex]1v = {360}^{o} [/tex]
Centesimal (C)
[tex]1v = {400}^{g} [/tex]
Radianes (R)
[tex]1v =2\pi \: rad[/tex]
La formula:
[tex] \frac{S}{360} = \frac{C}{400} = \frac{ R}{2\pi \: rad} [/tex]
Fórmula general:
[tex] \frac{S}{180} = \frac{ C }{200} = \frac{R}{\pi \: rad} = k[/tex]
De lo cual hacemos lo siguiente
S= 180k
C = 200k
R = πk
[tex] \frac{2\pi + 3R}{2\pi - 3 R} = \frac{ C +S }{C - S } [/tex]
Reemplazamos:
[tex] \frac{2\pi + 3\pi \: k}{2\pi - 3\pi \: k} = \frac{200k + 180k}{200k - 180k} [/tex]
Factorizamos π
[tex] \frac{\pi(2 + 3k)}{\pi(2 - 3k)} = \frac{380k}{20k} [/tex]
Simplificamos π y k
[tex] \frac{2 + 3k}{2 - 3k} = \frac{380}{20} [/tex]
[tex] \frac{2 + 3k}{2 - 3k} = 19[/tex]
2 + 3k = 19(2 - 3k)
2 + 3k = 38 - 57k
3k + 57k = 38 - 2
60k = 36
Sacamos sexta
10k = 6
k = 6/10
Pide en radianes entonces lo reemplazamos
R = π k
R = π 6/10
R = 6π /10 Rpta.
Espero haberle ayudado :-)
