OG Quantitative Review: Mistake in Question? [#permalink]
11 Oct 2005, 10:24
This is my first posting on gmatclub, so please be nice. Has anyone looked at Question#117 (DS) on page 157 of new OG Quantitative Review. I think the question is incomplete, shouldn't the Angle BAD be listed as x degrees on the graph? Otherwise, I think you can't solve the problem.
A little tricky to post, but I will try [#permalink]

The figure might be difficult for me to reproduce, but I will try to describe it. The questions is:
In triangle ABC above, what is the length of side BC?
1) Line segment AD has length 6.
2) x = 36
ABC is a triangle, with B being the vertex. From the vertex B draw a line that meets the base BC at D. The angle BDC and BCD are given to be x degree. That is BDC is an isoceles triangle. No other angle information is given.
