Suppose both cups are poured at the same time, and both are left sitting in the room that is 75°f. but this time,
milk is immediately poured into cup 2, cooling it to an initial temperature of 162°f.
a. use newton’s law of cooling to write equations for the temperature of each cup of coffee after tt minutes has
elapsed.

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.
