Question

Converta π/15 em graus

Answer 1

Radianos para Graus

Primeiro devemos lembrar que π = 180º

$\mathtt{n\º~~~~~~graus} \\ \\ \mathtt{\dfrac{\pi}{15}~~~~~~~~~~x} \\ \\ \mathtt{~\pi~~~~~~~~~~180} \\ \\ \mathtt{Multiplicar~cruzado} \\ \\ \mathtt{\pi x = 180~.~\frac{\pi}{15}} \\ \mathtt{\pi x = \frac{180\pi}{15}} \\ \mathtt{\pi x = 12\pi} \\ \mathtt{x = \frac{12\pi}{\pi}} \\ \mathtt{x = 12^o} \\ \\ \\ \boxed{\boxed{\mathtt{Resposta: 12^o}}}$
