How? It is yet to be proved analytically how the vertex angle A is equal to (pie)/7 radians i.e. 180/7 degrees.

The value of A (180/7 degrees), as claimed , has not been worked out analytically. The solution given by Deep Thought is a numerical solution. If the answer is exactly 180/7 degrees, it stands to reason that it can be proved so analytically. Numerical solution can give approximation to 180/7 degrees up to 30 or 40 decimal places or more but that is not an exact solution.
