Answer 1

Resposta:

1)

a).S= (8-2)180

S= 6x180

s= 1080°

b) S= (9-2)180

S= 7x180

S= 1260°

c) S= (7-2)180

S= 5x180

S=900

d) S= (12-2)180

S= 10x180

S= 1800

2) a) x+35+70=180

x+105=180

x=180-105

x=75

b) x+50+70+110=360

x+230=360

x=360-230

x=130

c) x+90+35=180

x+125=180

x=180-125

x=55

d) x+70+40=180

x+110=180

x=180-110

x=70

3) x=180-75

x=95

y=180-120

y=60

z+y+x=180

z+60+95=180

z+155=180

z=180-155

z=25

4) x+2x+3x=180

6x=180

x=180/6

x=30

5) primeiro o debaixo

15+90+y=180

105+y=180

y=180-105

y=75

90-75=15

x+15+50=180

x+65=180

x=180-65

x=115

6) C

espero ter ajudado
