The angle in the dilated figure is the same as the original angle in each case, a fact that should be confirmed by the way the answer choices are shown.
∠A = ∠A'
... 4x -4 = 51 -x
... 5x = 55
... x = 11
∠A = 4·11 -4 = 40 . . . . . . doesn't match any offered choice
___
∠B = ∠B'
... 6x -1 = 4x +21
... 2x = 22
... x = 11
... ∠B = 6·11 -1
... ∠B = ∠B' = 65 . . . . . matches selection D)
_____
∠C = ∠C'
... 8x -13 = 6x +9
... 2x = 22
... x = 11
... ∠C = 6·11 +9 = 75
... ∠C = ∠C' = 75 . . . . . matches selection D)

Answer:
dvd cost $12 each
book cost $1 each
Step-by-step explanation:
3d + 4b = 40
d + 6b = 18
substitution method:
d = 18-6b
3(18-6b) + 4b = 40
54 - 18b + 4b = 40
-14b = -14
b = $1
d + 6 = 18
d = $12
