Three triangular flower beds are placed so their tips meet at one point P. Each bed is identical, and the angles meeting exactly fill the space around P (360°). Each bed's angle at P is the largest angle of an isosceles triangle whose two equal base angles are 30° each. How many such identical beds fit exactly around P?
