Answer 1

1st ans. 180-130=50
2nd ans. 2x+20=180 , 2x=160 ,x=80
3rd ans. x=57
4rth ans.2x+18=180 , 2x=162, x=81
6th ans.3x=180 ,x=60

Answer 2

Answer:

a)180-130=50

c)57-oppsite angles

f)2x+x=3x

180/3=x

60=x

180-130=50

2x+20=180

2x=160

x=80

b) 2x+20=180

2x=160

x=80

d)2x+18=180

2x=162

x=81
