Again you don’t need to answer all of them but if you can do some that would be wonderful! Find the value of y that makes lines u and v parallel,

THANKS !

17)  x=7

18) x= -26

19) x= -8

20) x= 6

Step-by-step explanation:

17) is congruent

18) is supplementary

19) is congruent

20) is congruent

Q17. 6x+8=50 (alt angles, u//v)

6x=50-8

=42

x=42÷6

=7

Q18. 80°+x+106°=180° (int angles, u//v)

x+186°=180°

x=180°-186°

=-6

Q19. x+68=60 (vert opp angles)

x=60-68

=-8

Q20. 20x=120°

x=120÷20

=10

46.2+112.3

step-by-step explanation:

4/6 = 2/3

so it should take 3/3 hours per man. so 9 hours is the answer 3*3 =9
