Answer 1

Propiedades:

Radianes a sexagesimal:

$\frac{\pi }{x} rad$ ($\frac{180}{\pi rad}$) = $\frac{180}{x}$°

Centesimal a sexagesimal:

$x^{g}$ x $\frac{9}{10}$ = $\frac{9x}{10}$

Solucion:

Convertir a unidad sexagesimal:

$\frac{\pi }{5} rad$ ($\frac{180}{\pi rad}$) = $\frac{180}{5}$ = 36°

$\frac{5\pi }{12}rad$ ($\frac{180}{\pi rad}$) = $\frac{180.5}{12}$ = $\frac{900}{12}$ = 75°

$50^{g}$ ($\frac{9}{10}$) = $\frac{50.9}{10}$ = $\frac{450}{10}$ = 45°

Se plantea:

K = $\frac{36 + 54 }{75 - 45}$

K = $\frac{90}{30}$

K = 3
