I got this wrong in sparknotes
see diagram at http://geocities.com/cometosmeagol/
it says:
AB||CD
column a is x
column b is y
now, the angle x looks greater than y, but that is not mentioned. Also, there is no "figure is not drawn to scale" note. So, can't I answer A because x is supposed to be greater?

That can't be a triangle if that figure is to scale.

The side opposite "x" isn't as long as the side opposite 20 degrees. In other words, that would make "x" less than 20, which would make "y" more than 160 deg. in order for the 3 angles to sum 180. According to the picture, "y" isn't anywhere near being obtuse. THAT FIGURE IS NOT DRAWN TO SCALE.

thanks neo. the guy who made this question was stupid. but, let's say the 20 deg angle had an acceptable value, something like 60 deg or close. then, would you guess out the answer as x greater than y if its given the figure is to scale?

Unless I miss something, the answer should be D.

x and y could have any value between 1-159, as long as they total 160.
