INE>INE> yº zº
A D
In the figure shown, line segment AD is parallel to line segment BC. What is the value of x?
(1) y = 50
(2) z = 40
A. Statement (1) ALONE is sufficient, but statement (2) alone is not sufficient.
B. Statement (2) ALONE is sufficient, but statement (1) alone is not sufficient.

图形无法完全贴上，是这样的，B-C平行于A-D，在我看到的图上，角y指角C-A-D，角z指角C -D-A，x是B-C-D。
不知道是我的看图有问题还是答案有问题，答案是A，我选择C。为什么呀？谢谢。 |
