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