Question

pasar estos angulos a radianes
a) 12º b)180º c)-60º

Answer 1

1o. REGLA DE 3:

(PI/180)=(X/12)                                 ( PI/180)=(X/180)               ( PI/180)=(X/60)

2o. DESPEJAMOS X:

X= 12PI/180                                     X=180PI/180                        X=(60 PI)/180       
  = PI/15                                          =PI                                         X=60PI/180
  = .20944                                     =3.1416                            X=PI/3
Buscamos el equivalente decimal con calculadora
  =.20944                                       =3.1416                          X= 1.0472
