If `Delta = a^(2)-(b-c)^(2), Delta` is the area of the `Delta ABC` then `tan A =` ?

If Delta =a^(2) -(b-c) ^(2), where Delta is the area of the triangle ABC, then tan A is equal to-

If Delta = a^(2) - (b-c)^(2) where Delta is the area of triangle ABC, then tan A is equal to -

If Delta = a^2 - ( b-c)^2 where Delta is the area of triangle ABC then tan A is equal to

If Delta =a^2-(b-c)^2 , is the area of the triangle ABC, then tan A=

In Delta ABC ,if a=2, B=120^(@),C=30^(@) then area of Delta ABC is

In a triangle ABC. If triangle^(2) = (a^(2)b^(2)c^(2))/(2(a^(2)+b^(2)+c^(2)) , where triangle is the area of the triangle, then the triangle is

In Delta ABC, (b+c-a) tan (A//2) =

In Delta ABC , tan A + tan B+ tan C=
