Answer:
7. x=40
8. x=35
9. x=110
10. x=15
Step-by-step explanation:
alternate interior is congruent
2x=80 (divide both side by 2)
x=40
same side interior is supplementary (180)
2x+110=180
2x=180-110 (transpose)
2x= 70 (divide both side by 2)
x=35
corresponding angle is congruent
100=x-10
100+10=x (combine similar term or transpose)110=x
x=110
3x+15=60
3x=60-15
3x=45
x=15
