What is cone angle? - Answers
The apex angle is the angle in a cone that the apex, or point, of the cone takes. This is measured from two opposite sides of the cone, which is found by drawing a line from the apex to the center of the circular base, then drawing a plane through this line and using the lines of the plane's intersection of the cone to measure the angle.

How to Calculate the Height of a Building | Apex Group
Procedure: We know, Tangent = The ratio of the opposite side to the adjacent side. Which means tanθ = Opposite side/Adjacent side. here θ = 30º. So tan30º = Opposite side/Adjacent side = x/d = x/3000. x = tan30º x 3000 = 0.577 x 3000 = 1732 feet. ∴ The height of the building is 1732 feet. Building calculate height.
