Question

2x+50+90=180
X+60+90=180
X+10+x-20+90=180
30+x+90=180
2x+120=180

Answer 1

a)
2x +140 = 180
2x = 180-140
2x = 40
x = 40/2
x = 20

b)
x+150 = 180
x = 180-150
x = 30

c)2x+80 = 180
2x = 180-80
2x=100
x=100/2
x = 50

d)
x+120 = 180
x = 180 - 120
x = 60

e)
2x+120 = 180
2x = 180-120
2x = 60
x = 60/2
x = 30.
