Explicação passo-a-passo:

Multiplica por π e divide por 180:

Letra A:

= 20 × π/180

= 20π/180

= 2π/18

= π/9

Letra B:

= 36 × π/180

= 36π/180

= π/5

Letra C:

= 60 × π/180

= 60π/180

= 6π/18

= π/3

Letra D:

= 80 × π/180

= 80π/180

= 8π/18

= 4π/9

Letra E:

= 120 × π/180

= 120π/180

= 12π/18

= 2π/3

Letra F:

= 160 × π/180

= 160π/180

= 16π/18

= 8π/9

Letra G:

= 212 × π/180

= 212π/180

= 53π/45
