The mass of two objects are listed below. Michael says that the mass of object B is 25,000,000 times greater than the mass of object A. Ana says that the mass of object B is 25
times greater than the mass of object A. Compare the masses of objects A and B to decide
who is correct. Then find the error that the other person most likely made. *
(2 points)
Object A : 1.325 x 10-4 kg, Object B : 3.3125 x 103 mg

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.
