In `Delta`ABC, if tan `(A)/(2) = (5)/(6)` and tan `(C )/(2) = (2)/(5)`, then show that a,b,c, are in A.P.

In DeltaABC," if "tan""(A)/(2)=(5)/(6) andtan""(C)/(2)=(2)/(5), then show that a, b, c, are in A.P.

If in Delta ABC, tan.(A)/(2) = (5)/(6) and tan.( C)/(2)= (2)/(5) , then prove that a, b, and c are in A.P.

If in Delta ABC, tan.(A)/(2) = (5)/(6) and tan.( C)/(2)= (2)/(5) , then prove that a, b, and c are in A.P.

If in Delta ABC, tan.(A)/(2) = (5)/(6) and tan.( C)/(2)= (2)/(5) , then prove that a, b, and c are in A.P.

In a Delta ABC If tan"" (A )/(2 ) = (5 )/(6) , tan ""(C )/( 2) = (2)/(5) then

In a Delta ABC, tan.(A)/(2) = (5)/(6), tan.(C )/(2) = (2)/(5) , then :

In Delta ABC tan "" ( A)/(2) = ( 5)/( 6) , tan "" ( C )/(2) = (2)/(5) then a,b,c are such that

In a Delta ABC, If tan .(A)/(2)=(5)/(6) and tan .(B)/(2) =(20)/(37) , then show that tan ((C)/(2))=(2)/(5)

In a DeltaABC , if tan""(A)/(2)=(5)/(6),tan""(C )/(2)=(2)/(5) , then a)a, c, b are in AP b) a, b, c are in GP c)b, a, c are in AP d)a, b, c are in AP

If tan ""(A)/(2) = (5)/(6) , tan "" (B)/(2) = ( 20 )/( 37) then show that tan "" (C )/(2) = (2)/(5) . Also show that a,b,c are in A.P.
