The triangle

ABC

is isosceles with

AB=AC

, and

\angle{BAC}<60^{\circ}

. The points

D

and

E

are chosen on the side

AC

such that,

EB=ED

, and

\angle{ABD}\equiv\angle{CBE}

. Denote by

O

the intersection point between the internal bisectors of the angles

\angle{BDC}

and

\angle{ACB}

. Compute

\angle{COD}
