Ling invested some money at 10% interest. Ling also invested $163 more than 3 times that amount at 14 %. How much is invested at each rate if Ling receives $2334.74 in interest after one year? (Round to
two decimal places if necessary.)

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.
