Hi Mark. Perhaps you can help.



In my elegant, or so I thought, theory the two ramps should have been 1 to 2 and 1 to 2.618 or angles of 26.565 and 20.90. Now the Upper entrance is 26 degrees 28 minutes or 26.46667 is reasonably close and the connecting passageway could be either 1/2 of 1/2 of 90 or 22.5 but what I can' figure out is how either 20 degrees 40 minutes or 20 degrees 19 minutes fit in. The latter yields a tan (run to rise) 0.39022 or 1 to 2.56267 while the former gives us 0.39727458 and rise to run of 1 to 2.517151 ... so if this one is correct it could be 1 to 2.5 but this really doesn't fit in that I can see.

Any ideas either Mark or Keith ?
