If someone would like to grease my palm with just a tiny fortune I'm prepared to reveal the results of National Lottery draws to them about 8 hours before they're drawn!
Unfortunately I can't enter the draws myself because us Aussies are banned from entering...obviously!

I don't know GFs, C++ or Python (I know some BASIC and a tiny bit of M), but the Python code from StackExhange was clear enough for me to be able to modify it to suit the two puzzles.
#544 Re: Help Me ! » Combinations and Permutations » 2016-05-11 03:40:55
Hi;
I adapted a Python code I found on SE and got 4,562 for the 6 coins (in 0.02 seconds) and 327,631,321 for the 9 coins (in 6.1 minutes).
#545 Re: Help Me ! » angles help » 2016-05-07 23:23:09
Hi Bob;
I didn't know that the "external angle of a triangle XBC is sum of two internal opposites", and I came to x = y + z differently:
BXC = 180 - x
∴ y = 180 - z - (180 - x) => y = x - z (or, x = y + z)
The rest was the same.
Ah...the 'exterior angle theorem' is right here.
#546 Re: Help Me ! » angles help » 2016-05-07 02:15:20
I am unable to understand the discussion. it was about calculation of an angle but I am unable to follow the thread.
Post #4 is just a chant that's popularly used in support of a favourite something or other, which is usually a person but in this case is the freeware geometry program Geogebra, for which some of us here on MIF 'affectionately' use the "Gebra" abbreviation (I tend to use "G"). "M" for "Mathematica" is another example.
bobbym and I like to use G to help solve geometry problems, but on this occasion I felt the need (urge?) to go the manual route: pen and paper.
So, once we had both solved the problem and confirmed the OP's answer, our discussion turned to the weightier matter ( 
) of which solution method to use: software or 'hard'ware [sic]:
So, you did it the hard way.

Sorry...can't reply right now, coz Nadal just broke Murray who was serving for the match, and they're back on serve again.
Edit: It's over...Murray broke right back again, for his second win ever against Nadal on clay.
#548 Re: Help Me ! » angles help » 2016-05-07 01:01:43
Yes...wanted to see if I could still rough it, with no mod cons. 
#549 Re: Help Me ! » angles help » 2016-05-07 00:49:46
Did it without G, but got it to check my work. I hadn't realised until then that there can be a variety of shapes.
