How to do this when d = 21 3/8ths inches?

What if 10 foot sides are wanted?

[@hudsonsoul1121]

10 foot sides. 10 foot x 45(degrees) sin equals 7foot and 7\8. 7foot and 7\8 x 2 equals 14foot 1inch and 11\16. Add the 10foot equals 24 feet 1inch and 11\16 which will be your span.
Hope this makes sense even if l am 2 years late. Alternatively just add 141.6% to your side length.

[@fightswithspirits915]

@@hudsonsoul1121 lol yes. Thank you though.

*applause sound*

[@hudsonsoul1121]

Octagon lengths = span(1800) - 58.6%
Example 1800 span
-58.6%
1054.8
=745.2

Lies again? Rome Roma Evil Angel

[@hudsonsoul1121]

@@NazriB you must be doing it wrong

[@gprooftheory]

That is hard to do in the construction field, you can get the same thing using the hypotenuse of the main square

[@hudsonsoul1121]

Subtract 58.6% from span (parallel sides, not points) and this will give your length and then you can mitre the 22.5.

[@gprooftheory]

You can minus D from the hypotenuse Q to S x 1.414 = S to F the distance left over from Q to S x 2 = G to F

Damn.. i can't understand at all..
