a) 4π/3 rad
b)11π/9 rad
c)π/4 rad
d)7π/6 rad

Answer 1

a )
 1$\pi$ ⇒ 180 GRAUS
$\frac{4}{3pi}$ ⇒ x
x = ($\frac{4}{3}) * 180 = 240 graus$

b ) $\pi$⇒180 º
 $\frac{11pi}{9}$⇒   x
x=(11π/9.180)/π
x=(11π.20)/π
x=220 graus 

c)180/4 =  45 graus

d)
$\pi$ ⇒180
$\frac{7*180}{6}$
$\frac{1260}{6}$
210 graus
