Question

POR FAVOR ME AJUDEM!!! URGENTE

Answer 1

$\pi = 180graus$

$A) \frac{ 10 \pi}{9}rad = 10*180/9 = 200 graus \\ \\ B) \frac{11 \pi }{8}rad = 11 *180/8 = 247,30" graus \\ \\ C) \frac{\pi}{9}rad = 180/9 = 20 graus \\ \\ D) \frac{\pi}{20}rad = 180/20 = 9 graus \\ \\ E) \frac{4\pi}{3}rad = 4*180/3 = 240 graus$

Answer 2

a maneira mais facil é substuir PI por 180°

a) 10 · (180°)/9 = 1800/9 = 200°

b)11 · (180°)/8 = 1980/8 = 247°30“

c) 180°/9 = 20°

d) 180°/20 = 9°

e) 4 · (180°)/3 = 720/3 = 240°
