furniture worth ​$10,000. The house has a mortgage of ​$50,000 and the cars have outstanding loans of ​$2,000 each. Utility​ bills, totaling ​$150 for this​ month, have not been paid. Calculate or use Worksheet 4 to determine their net worth and explain what it means. How would the​ Lees' age affect your assessment of their net​ worth?

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.
