I'm not a whiz at proofs but I think I know the answers.
A. Given
B. Alternate Interior Angles Theorem
C. Transitive Property of Equality
D. AAS Postulate
Since the angles two and four are vertical they have to equal each other so you put that in an equation and solve for x:
7x+7=140
-7 -7
7x=133 divide both sides by 7
x=19
Since angles 3 and 4 have to equal 180 to make a straight line they have to add together and equal 180 and solve for y:
5y+140=180
-140 -140
5y=40 divide both sides by 5
y=8
So your answer is x=19 and y=8
It takes 4 liters to make a gallon, there are 15 liters so therefore that would be 3 gallons and 2 liters.
