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