In `DeltaABC`, If `x= tan((B-C)/2) tan(A/2),y= tan((C-A)/2)tan(B/2), tan((A-B)/2) tan(C/2)` , then `x+y+z` (in terms of x, y, z only) is

In DeltaABC , If x= tan((B-C)/2) tan(A/2),y= tan((C-A)/2)tan(B/2), z=tan((A-B)/2) tan(C/2) , then x+y+z (in terms of x, y, z only) is

In Delta ABC, If x=tan((B-C)/(2))tan((A)/(2)),y=tan((C-A)/(2))tan((B)/(2)),tan((A-B)/(2))tan((C)/(2)) then x+y+z (in terms of x,y,z only ) is

In Delta ABC, if x=tan((B-c)/2)tan""A/2,y=tan((C-A)/2)tan""B/2,z=tan((A-B)/2)tan""C/2 , then x+y+z (In terms of x,y,z only ) is

In Delta ABC , if x=tan((B-C)/(2))tan.(A)/(2),y=tan((C-A)/(2))tan.(B)/(2) and z=tan((A-B)/(2))tan.(C)/(2) then (x+y+z)= .

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

v) tan(A/2)tan(B/2)+tan(B/2)tan(C/2)+tan(C/2)tan(A/2)=1

In DeltaABC , tan""((A+B)/(2))*tan""(C)/(2)=
