Question

find x° if ab || cd ​

Answer 1

Answer:

x=40°

Step-by-step explanation:

Draw FG||AB||CD,

120°+1=180° ( co-interior angles since AB||FG )

1=180°-120°

1=60°

100°+2=180° ( co-interior angles since CD||FG )

2=180°-100°

2=80°

1+x+2=180° ( straight angles )

60°+80°+x=180°

140°+x=180°

x=180°-140°

x=40°
