For ΔABC, ∠A = x + 30, ∠B = 2x - 4, and ∠C = 4x. If ΔABC undergoes a dilation by a scale factor of 1 2 to create ΔA'B'C' with ∠A' = 2x + 8, ∠B' = x + 18, and ∠C' = 5x - 22, which confirms that ΔABC∼ΔA'B'C by the AA criterion? A) ∠A = ∠A' = 50° and ∠B = ∠B' = 36° B) ∠A = ∠A' = 26° and ∠C = ∠C' = 44° C) ∠A = ∠A' = 52° and ∠C = ∠C' = 88° D) ∠B = ∠B' = 46° and ∠C = ∠C' = 100°
