For δabc, ∠a = 3x - 8, ∠b = 5x - 6, and ∠c = 4x + 2. if δabc undergoes a dilation by a scale factor of 1 2 to create δa'b'c' with ∠a' = 2x + 8, ∠b' = 90 - x, and ∠c' = 5x - 14, which confirms that δabc∼δa'b'c by the aa criterion? a) ∠a = ∠a' = 37° and ∠b = ∠b' = 69° b) ∠a = ∠a' = 22° and ∠c = ∠c' = 42° c) ∠b = ∠b' = 37° and ∠c = ∠c' = 33° d) ∠b = ∠b' = 74° and ∠c = ∠c' = 66°
