Question

1 - Transforme os ângulos:
a) 570° para radianos
b) 4/5π radianos em graus


me ajudem por favor ​

Answer 1

Resposta:

a) = 19π/6

b) = 225°

Explicação passo-a-passo:

a) 570°

$\cfrac{180}{570} = \cfrac{\pi \ rad}{x\ rad} \\\\\\180x = 570\pi \\\\\\x = \cfrac{570}{180}\ \pi\ rad\\\\\\570^o = \cfrac{19\pi }{6}$

b) 4/5π

$\cfrac{5\pi }{4} \\\\\\\cfrac{180.5}{4} \\\\\\\cfrac{900}{4} \\\\\\\cfrac{5\pi }{4} =225^o$
