A)2x+x=180 3x =180 x =180/3 x =60 b)34+2x+40=180 2x =180-(34+40) 2x =106 x =106/2 x =53 c)60+30+2x=180 2x =180-(60+30) 2x =90 x =90/2 x =45 d)3x+2x+x=180 6x =180 x =180/6 x =30
3x =180
x =180/3
x =60
b)34+2x+40=180
2x =180-(34+40)
2x =106
x =106/2
x =53
c)60+30+2x=180
2x =180-(60+30)
2x =90
x =90/2
x =45
d)3x+2x+x=180
6x =180
x =180/6
x =30
