Answer:
20
Step-by-step explanation:
1449÷72.45=20
Since they're vertical angles, they're equal in degree measure
since they're equal, we can make the two expressions equal to each other
5a - 1 = 2a + 20
add 1 to both sides
5a = 2a + 21
subtract 2a from both sides
3a = 21
divide both sides by 3a
a = 7
now, plug the answer you found for a into one of the two expressions
5a - 1 becomes (5*7) - 1, which equals 34
to double check that they're equivalent (since they're vertical angles)
2a + 20 becomes (2*7) + 20, which equals 34
both angles are 34 degrees!

Answer:
d
Step-by-step explanation:
Width be X, length is X+15
area of garden = x(x+15)
area of sidewalk = x(x+15) - (x-4)(x+11) = 632
X^2 + 15X - X^2 - 7X + 44 = 632
8X = 632-44 =588
X= 73.5 >> WIDTH and LENGTH = 88.5
