IMO E.

I would choose A, if i am able to prove BAD and ABD are each x such that their sum equals 2x(exterior angle).

If anybody could prove the above, please post.

i think angle BAD is X.
it is a BAD case of printing mistake.
let me know if that makes sense

Not sure

by enniguy » Mon Jul 28, 2008 12:42 am
IMO C.

Reasoning:
1. consider any triangle BDC. BDC is an isosceles triangle from question.
Fixing AD = 6, we can vary the height of the triangle BDC varying x. So we cant determine BC.

[Think of it like you can just pull point B up and down with sides as strings]

INSUFFICIENT.

2. Now, if you keep the angle 2x the same, i.e 72 degrees, then you can vary AD to any length and change the size of the triangle (Similar triangles keeping the ratio x:2x:2x).

INSUFFICIENT.

Together, if you fix the angle x and AD, then you cant vary the height of the triangle hence you will be able to find BC.

Please correct me if i am wrong
