An isosceles triangle of wood is placed in a vertical plane, vertex upwards, and faces the sun. If 2a be the base of the triangle, h its height and `30^@` the altitude of sun, then the tangent of the angle at the apex of the shadow is

An isosceles triangle of wood of base 2a and height h is placed with its base on the ground vertex directly above . The triangle faces the sun whose altitude is 30^(@) . Then the tangent of the angle at the apex of the shadow is

An isosceles triangle of wood of base 2a and height h is placed with its base on the ground vertex directly above. The triangle faces the sun whose altitude is 30^@ . Then, the tangent of the angle at the apex of the shadow is
