Question

Transforme em graus​

Answer 1

Resposta:

Explicação passo-a-passo:

Pi  rad ..................................................180 graus

Pi/2 rad  .................................................x

Pi/(Pi/2 )   =  180/x

multiplica em cruz

Pi * x =  180  * Pi/2

Pix    =  180Pi/2

xPi  = 90Pi

x = 90Pi/Pi   corta Pi

x =  90 graus

b

Pi  rad  ..........................................180 graus

Pi/8 rad .........................................x

Pi / ( Pi/8)    = 180/x

idem

Pi * x   = 180 *  Pi/8

Pix =  ( 180Pi/8 )

Pix = 22,5Pi

x = 22,5 Pi/Pi   corta Pi

x = 22,5 graus

c

Pi rad .............................................180graus

5Pi/9 .................................................x

Pi/ (  5Pi/9 )    = 180/x

Pi  * x   =  ( 5Pi/9) * 180

Pix =   ( 5 * 180)/9 Pi  ou(  900/9) Pi

Pi x = 100 Pi

x = 100Pi/Pi   cort Pi

x = 100  graus

d

Pi  rad .............................................180 graus

3Pi/40 .............................................x

Pi / ( 3Pi/40 )  = 180/x

Pi * x =   180 ( 3Pi/40 )

Pix  =  ( 180 *  3 )/40  Pi

Pix =  540/40 Pi

Pix =13,5 Pi

corta Pi

x = 13,5 graus

e

Pi  rad ..........................................................180  graus

11Pi/45 ............................................................x

Pi/ ( 11Pi/45)  =  180/x

Pi * x =  180 ( 11Pi)/45   ou  ( 1980/45) Pi ou 44 Pi

x =  44Pi/Pi   corta Pi

x = 44  graus
