HURRY! WILL GIVE BRAINLIEST! If m∠ABC = 70°, what is m∠ABD? Justify your reasoning. A)Using the addition property of equality, 40 + 70 = 110, so m∠ABD = 110°. B)Using the subtraction property of equality, 70 − 30 = 40, so m∠ABD = 30°. C)Using the Angle Addition Postulate, 40 + m∠ABD = 70. So, m∠ABD = 30° using the subtraction property of equality. D) Using the Angle Addition Postulate, 40 + 70 = m∠ABD. So, m∠ABD = 110° using the addition property of equality.
