>this >>2605107 is better

it's more detailed and meticulous, but that's not the same as "better". it just means it's cluttered and poorly planned.

cba to try to draw it out, but if you let the three points on the horizontal line be P,Q,R, then by drawing lines and playing with trapezoids and shit, you can see that

<span class="math">PQ = \sqrt(4AB)
QR = \sqrt(4BC)
PR = \sqrt(4AC)[/spoiler]

so

<span class="math">\sqrt(4AC) = \sqrt(4AB) + \sqrt(4AC)[/spoiler]

and now divide by <span class="math">\sqrt(4ABC)[/spoiler].
