Resposta:

1)a) 4π/3

b) 2π/3

c) π

d) 5π/4

e) 3π/4

f) 5π/3

g) 7π/6

h) 5π/6

i) 11π/6

2)a) 240°

b) 120°

c) 180°

d) 225°

e) 135°

f) 300°

g) 210°

h) 150°

i) 330°

Explicação passo-a-passo:

π = 180°

1)a) π/3 + π = π + 3π = 4π/3

3

b) π - π/3 = 3π - π = 2π/3

3

c) 2π - π = π

d) π/4 + π = π + 4π = 5π/4

4

e) π - π/4 = 4π - π = 3π/4

4

f) 2π - π/3 = 6π - π = 5π/3

3

g) π/6 + π = π + 6π = 7π/6

6

h) π - π/6 = 6π - π = 5π/6

6

i) 2π - π/6 = 12π - π = 11π/6

6

2)a) π/3 + π = 180/3 + 180 =

60 + 180 = 240°

b) π - π/3 = 180 - 180/3 =

180 - 60 = 120°

c) 2π - π = 2.180 - 180 =

360 - 180 = 180°

d) π/4 + π = 180/4 + 180 =

45 + 180 = 225°

e) π - π/4 = 180 - 180/4 =

180 - 45 = 135°

f) 2π - π/3 = 2.180 - 180/3 =

360 - 60 = 300°

g) π/6 + π = 180/6 + 180 =

30 + 180 = 210°

h) π - π/6 = 180 - 180/6 =

180 - 30 = 150°

i) 2π - π/6 = 2.180 - 180/6 =

360 - 30 = 330°
