For δabc, ∠a = 2x - 2, ∠b = 2x + 2, and ∠c = 5x. if δabc undergoes a dilation by a scale factor of 1 2 to create δa'b'c' with ∠a' = 58 - x, ∠b' = 3x - 18, and ∠c' = 120 - x, which confirms that δabc∼δa'b'c by the aa criterion? a) ∠a = ∠a' = 38° and ∠b = ∠b' = 42° b) ∠a = ∠a' = 19° and ∠c = ∠c' = 21° c) ∠b = ∠b' = 18° and ∠c = ∠c' = 50° d) ∠b = ∠b' = 32° and ∠c = ∠c' = 75°
