d = 0.78125 (B-D1)
D1 = B-1.28 d
Subtract (D1-1.28 d) from both sides:
1.28 d = B-D1
Divide both sides by 1.28:
d = 0.78125 (B-D1)
here's how I did it: [URL]http://www.wolframalpha.com/input/?i=Solve+D+%3D+B+-+1.28d+for+d[/URL]
On reflection, not that hard.
((D+B)/-1.28)=d
Don't listen to anyone else, It's 51
Figured it to be 13.52512
what the fuck is this i'm only in geometry

Does this help?
