EXAMPLE

(A)=0.7578747639260239988121867474270095303467925401944...

(A)=(4*sqrt(6-3*sqrt(3)))/(3+sqrt(3))

(B)=2-(2/3)sqrt(3)

(C)=sqrt(6)-sqrt(2)

MATHEMATICA

a = 1; b = Sqrt[3]; c = 2;

f = 2 a*b/(a + b + c);

x1 = Simplify[f*Sqrt[a^2 + (b + c)^2]/(b + c) ]

x2 = Simplify[f*Sqrt[b^2 + (c + a)^2]/(c + a) ]

x3 = f*Sqrt[2]
