The Great Pyramid of Cheops at Giza in Egypt has a square base of side length 230 m. The angle of elevation of one
triangular face is 52Β°. Determine the measure of the angle π between the height and one of the edges where two triangular faces meet.

The height h is found via
h/115 = tan52Β°
The diagonal of the base is 230β2
So,
sinπ = (115 tan52Β°) / (115β2) = tan52Β°/β2
h/115 = tan52Β°
The diagonal of the base is 230β2
So,
sinπ = (115 tan52Β°) / (115β2) = tan52Β°/β2
