B) X=10°

C)X= 40°

D) X=22°

E) X=160°

F) X=50°

G) X=88°

Explicação passo-a-passo:

A) 3x+20=2x+50

3x-2x=50-20

X=30

B) 3x+40=4x+30

4x-3x=40-30

x=10

C)3x+x+20=180

4x=180-20

4x=160

X=160/4

x=40

D)5x+3x+4=180

8x=180-4

8x=176

x=176/8

x=22

E) x+20=180

x=180-20

x=160

F)x+130=180

x=180-130

x=50

G)x+92=180

x=180-92

x=88
