Answer:
see below (I hope this helps!)
Step-by-step explanation:
Alternate exterior angles are congruent so we know that ∠2 ≅ ∠ 7. Vertical angles are also congruent so ∠7 ≅ ∠6. Consecutive interior angles are supplementary so we know that ∠6 and ∠4 are supplementary. Now, we can use the Transitive Property (this states that if a = b and b = c then a = c) to compare ∠2 and ∠4. In this case, a = ∠2, b = ∠7 and c = ∠6 so we know that ∠2 ≅ ∠6 and since ∠6 is supplementary to ∠4, we can use the Transitive Property again to conclude that ∠2 and ∠4 are supplementary.
X = 180 - 70 - ( 180 -120)
X = 180 - 70 - 60
X = 180 - 130
X = 50
The way I solved this problem was by subtracting 200-75 and getting 125. So he would need to mow 125 more lawns. To check your answer you can add 125+75 and get 200

1st: 2x-3 2nd: 2x-1 3rd: 2x+1 4th: 2x+3
adding the above you get 8x=184
