Question

ME AJUDEM PORFAVOOR !

Tranforme em graus o angulo de 4Π/5= rad .

Answer 1

$2 \pi$ $\text{rad}$ ⇒ $360^{o}$

$\dfrac{4 \pi }{5}$ $\text{rad}$ ⇒ $x$

$\dfrac{2 \pi }{ \frac{4 \pi }{5} } = \dfrac{360}{x}$

$2 \pi . \dfrac{5 }{4 \pi} = \dfrac{360}{x}$

$\dfrac{5 }{2} = \dfrac{360}{x}$

$\dfrac{1 }{2} = \dfrac{72}{x}$

$x=2.72$

$x= 144^{o}$

Answer 2

360º = 2$\pi$
x = 4$\pi$ /5
multiplica cruzado
2$\pi$ x = 288$\pi$
x = 288$\pi$ / 2$\pi$
corta $\pi$
x = 144º
