Tricky!!
The author of this question wants us to think that the line through the triangle is perpendicular to the base.
However, this would be an unwarranted conclusion, since we're not told that it's perpendicular (although it certainly looks perpendicular :-D )

If it were perpendicular, then x and y would be equal.
However, it's also possible that the line is NOT perpendicular in which case, x and y are NOT equal

D

This illustrates what Brent was talking about. You can have an isosceles triangle with two equal angles, and two equal sides, and still have two top angles formed by a non-perpendicular line, which have unequal angles.

As he said, obviously the question writer wants the viewer to jump to the conclusion that the line is perpendicular, even though it might not be because they didn't mark it as such.

So, as everyone else already mentioned, we can't say that A and B are equal because they might not be. So, D.
