There are two regular quadrangular pyramids with base side
and side edge
. They have a common side face and have no other common points. The cone has the same vertex
as the pyramids and touches them externally. Find the largest possible angle at the apex of the cone at which it is possible. (The angle at the apex of the cone is the angle between its generators in the axial section).
