[tex] \frac{\pi}{32}\times \frac{180}{\pi} = \frac{180}{32} [/tex]
Paso 2
[tex] \frac{180}{32} = (a + b + c) \\ 5.625= (a + b + c) \\ 5 + (0.625 \times 60) = (a + b + c) \\ 5 + 37 + (0.5 \times 60) = (a + b + c) \\ 5 + 37 + 30 = (a + b + c)[/tex]
a = 5; b = 37; c = 30
Paso 3
a + b + c = 5 + 37 + 30 = 72°
[tex]72 \times \frac{\pi}{180} = \frac{2\pi}{5} [/tex]
