Geometry Level 3

A tower stands at the center of a circular park. $$A$$ and $$B$$ are two points on the boundary of the park such that $$AB$$ subtends an angle of $$60^\circ$$ at the foot of the tower and the angle of elevation of the top of the tower from $$A$$ or $$B$$ is $$30^\circ.$$

Find the height of the tower.
