Mohammed wants to prove that circle c with center (-4,8) and radius d with center (4,-8) and radius 8. He plans to do so by mapping C onto D using a sequence of similarity transformations. Which sequence should he use?
A. Translation 8 units right and 16 up, then dilation with center(-4,8) and scale factor 2/3
B. Translation 8 units left and 16 units up, then dilation with center (-4,8) and scale factor 3/2
C. Translation 8 units left and 16 units down, then dilation with center (4,-8) and scale factor 3/2
D. Translation 8 units right and 16 units down, then dilation with center (4,-8) and scale factor 2/3

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.
