The height h is found via
h/115 = tan52°
The diagonal of the base is 230√2
So,
sin𝜃 = (115 tan52°) / (115√2) = tan52°/√2
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 52°. Determine the measure of the angle 𝜃 between the height and one of the edges where two triangular faces meet.
