Question

1 - Transforme para radianos as seguintes medidas. *
a) 210°
b) 780° ​

Answer 1

Resposta:

regra de très simples

a)

210     180

 x        π

180x = 210π

x = 210π/180

x = 7π/6

b)

780     180

 x         π

180x = 780π

x = 780π/180

x = 13π/3

Answer 2

Explicação passo a passo:

Pi = 3,14

180 graus >>>>>>>>>>>>>>>Pi rad

210 >>>>>>>>>>>>>>>>>>>> x

180/210 = Pi/x

em cruz

180 * x = 210 * Pi

180x= 210 * 3,14

180x = 659,4

x = 659,4/180

x = 3,66 rad>>>>> resposta>>

b

180 graus >>>>>>>>>>>>>>>>>>>>Pir rad

780 graus >>>>>>>>>>>>>>>>>>>>> x

180/780 =Pi /x

180 *x =780 * 3,14

180x = 2 449,2

x = 2 449,2 / 180

x=13,6 rad >>>>>resposta
