Calculate Arc Width by having length and rise

[ravetunes]

Hi there, is it possible to calculate the Arc width by only having the Arc Length and Rise?

Rise is the height of arc

Arc length = 1525

rise = 230

width = ?

just noticed your post there wsjackman, thanks for that ill see if i can make it work... but as i said that link to the calculator only needs the 2 inputs and it gave me the correct answer so there is a formula, is that formula you posted a working one or do you need the radius because i dont have it... any help would be great,...

The "See Below" on the webpage refers to...

Newton's Method works for (1-cos[x])/x = k (Case 3 above), with the initial start
x(0) = 2k,
and iteration
x(n+1) = x - (cos[x]+kx-1)/(-sin[x]+k).
