For δabc, ∠a = 8x - 10, ∠b = 10x - 40, and ∠c = 3x + 20. if δabc undergoes a dilation by a scale factor of 1 2 to create δa'b'c' with ∠a' = 6x + 10, ∠b' = 70 - x, and ∠c' = 10x 2 , which confirms that δabc∼δa'b'c by the aa criterion? a) ∠a = ∠a' = 70° and ∠b = ∠b' = 60° b) ∠a = ∠a' = 35° and ∠b = ∠b' = 30° c) ∠b = ∠b' = 54° and ∠c = ∠c' = 40° d) ∠a = ∠a' = 76° and ∠c = ∠c' = 53°
