As per question, Angle BDC = Angle BCD = 2x, therefore BC = BD.
Statement 1: AD = 6,
Angle ADB = 180-2x , so sum of Angle BAD and Angle ABD = 2x, but we cannot assume these two angles to be equal. So AD may not be equal BC. Therefore this statement is insufficient.
Statement 2: x=36, just knowing the angle would not help in determining the length of any side in this question. therefore insufficient.
Even with both the statements, we cannot get the length of BC.
Therefore (E). what is the OA?
