Simplify the polynomial. 4x^2 + 4 - 5x + x - 2x^2 + 8a) -2x^2 + 4x + 12b) -2x^2 - 4x + 12c) 2x^2 + 4x + 12d) 2x^2 - 4x + 12

If m∠abc = 70°, what is m∠abd? justify your reasoning.  using the addition property of equality, 40 + 70 = 110, so m∠abd = 110°.  using the subtraction property of equality, 70 − 30 = 40, so m∠abd = 30°.  using the angle addition postulate, 40 + m∠abd = 70. so, m∠abd = 30° using the subtraction property of equality.  using the angle addition postulate, 40 + 70 = m∠abd. so, m∠abd = 110° using the addition property of equality.
