```							a/sinA = b/sinB = c/sinC = ka= k/root2b= root3k/2a+ root2 b = k(1+root3)/root2 -----(eq 1) b/sinB =kb= sin 75 * kk= 2root b/(root3+1) Substitute value of k in equation 1) a + root c = 2b

```							a/sin45 = b/sin75 = c/sin60 = k a=k/√2.      b=ksin(45+30).         c=k√3/2                    b=k(√3+1)/2√2                i.e 2b=k(√3+1)/√2.  ------ (1)a+c√2 = k/√2 + k√3.√2/2            =k(1+√3)/√2            =2b.            (from 1)
