B=40 because you have to divide 3/5 on each side.
n=12 because 24/2=12
d=32 because you have to divide 1/4 on each side
x=12.25 because 36.75/3=12.25
x=9 because 5-14 on each side is 9
x-3 because 35-32=3
Since all reflections are inverse of itself, carrying any reflection about the same axis twice will carry the preimage back to itself.
Perimeter of the trapezoid = a + c + 2b
58 = a + c + 2b
Average of bases = (a + c)/2
19 = (a + c)/2
a + c = 38
Substituting (a + c) into the first equation:
58 = 38 + 2b
b = 10 in
We also know that:
c = 2b + 7
c = 2(10) + 7
c = 27 in
a + 27 = 38
a = 11 in
a = 11 in; b = 10 in; c = 27 in
