Izzy has obtained a 5/1 30-year arm to purchase a $165,000 home. the fixed-interest rate is 4.75%, followed by a 5% rate with a 1.5% margin. what will her new monthly payment be after the initial fixed period ends?
a. $1019.37
b. $1417.34
c. $1104.70
d. $1207.98

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.
