Question

6 people A B C D E and F are sitting on ground in a hexagonal shape is not at the send to B or c d is not adjacent to see or B and C are adjacent if is in the middle of DNC now a line is drawn connecting d2c and D to B . Then the circle is inscribed on the ground that touches the corners of the quadrilateral ABCD ,such that A,B,C and ,D lie on the circumference of the circle . angle BAC - one internal angle of any equilateral triangle and angle ACD - 20 degrees . Ac - Xcm and intersection of AC and BD is at O .Now find -. 1) angle AOD. 2). Length of chord BC 3) Area of Triangle AOD​

Answer 1

Answer:

The answer is option A

From the figure we can see that A and F are the only non-adjacent people
