The distance of planet saturn from the sun is 1.5 ⋅ 109 kilometers, and the distance of planet venus from the sun is 1.1 ⋅ 108 kilometers. about how many more kilometers is the distance of saturn from the sun than the distance of venus from the sun?

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.
