(See Plate iv.) Thequestion, therefore, now is,—standing at that pointof the floor of the subterranean chamber,—what isthe angular subtense therefrom, of the whole side ofthe Pyramid, in degrees of the Pyramid, or 250° tothe quadrant ? This question is fortunately very simple to com-pute ; for in the triangle A b c (Plate iv.), c b, thelength of the slant side of the Pyramid, or 7400British inches, is computed from the elements of thevertical height, angle at summit, and base-sidelength already given, in Division PI. 4-.
