500
What sequence of transformations maps rectangle ABCD onto rectangle A'B'C'D'?
Rotate 90o Clockwise, Reflect over y-axis, translation 6 units up, translation 6 units left (or equivalent).
500
What is the measure of angle ACB?
50o
500
Are any of the following lines (a, b, and c) parallel? How do you know?
Yes, a and c. The supplementary angle of 110o is 70o, so angle 2 is corresponding with the 70o angle at the top, making a and c parallel.
