... I did the trig and found 2.274192793.

The conclusion is that the triangle is a perfect 280 to 220 or 14 to 11 triangle leading to the seked. Interesting. ...

Hi O

Could you post the formulae so others, including myself, can check your work.

I would have preferred the Phi angle but yes 7/11 is equally interesting.

This makes the enclosed angle 51.8428 degrees

And makes the small angle at D equal to 15.9454 degrees with the angle at C 74.0546 (Angle at Meidum of that pyramid ?) and the remaining angle at C of 22.2118 [ (2/9) x 100 ]

If your work is correct I might have to jump over to the 5.5/7 camp

Cheers
Don Barone
