If `A, B and C` are three values lying in `[0, 2pi]` for which `tan theta = K` then `tan""(A)/(3) tan ""(B)/(3) + tan ""(B)/(3)tan ""(C )/(3) + tan ""(C )/(3)tan ""(A)/(3)` is equal to ___________.

IF A+B+C =pi , then tan ((A)/(2)) tan ((B)/(2)) + tan (B/2) tan (C/2) + tan (C/2 ) tan ((A)/(2)) is

If sin A : sin B : sin C = 3: 4: 5 then tan ""(A)/(2) : tan ""(B)/(2) : tan "" (C ) /(2) =

If A+B+C=pi , then tan((A)/(2))tan((B)/(2))+tan((B)/(2))tan((C)/(2))+tan((C)/(2))tan((A)/(2)) is equal to a) (pi)/(6) b)3 c)2 d)1

If A+B+C=pi, then the value of (tan ""A/2 tan ""B/2+tan ""B/2 tan ""C/2 + tan ""C/2 tan ""A/2) is-

If theta_(1),theta_(2),theta_(3) are three values lying in [0,2pi) for which tan theta = lambda , then the value of tan((theta_(1))/(3))tan((theta_(2))/(3))+tan((theta_(2))/(3))tan((theta_(3))/(3))+tan((theta_(3))/(3))tan((theta_(1))/(3)) is

In Delta ABC if tan(A/2) tan(B/2) + tan(B/2) tan(C/2) = 2/3 then a+c

In Delta ABC if tan((A)/(2))tan((B)/(2))+tan((B)/(2))tan((C)/(2))=(2)/(3) then a+c

In Delta ABC if tan(A/2) tan(B/2) + tan(B/2) tan(C/2) = 2/3 then a+c

If theta_(1),theta_(2),theta_(3) are three values lying in [0,3pi) for which tan theta = lambda , then the value of |tan((theta_(1))/(3))tan((theta_(2))/(3))+tan((theta_(2))/(3))tan((theta_(2))/(3))+tan((theta_(3))/(3))tan((theta_(1))/(3))| is
