In a `DeltaABC`, if `a=18, b = 24, c=30`, find : `tan (A/2) , tan( B/2), tan (C/2)`

If in DeltaABC, a=15, b = 36, c=39 , find tan (A/2)

In DeltaABC, a = 3, b = 5, c = 6 , find the value of : tan (A/2)

Find the area of DeltaABC if : a = 18, b = 24, C=30

In a DeltaABC ,a =5 , b= 4 , and tan(C/2)=sqrt(7/9) , then c =

. In a DeltaABC, If tan (A/2) , tan(B/2), tan (C/2) , are in H.P.,then a,b,c are in

In any Delta ABC , prove that : ((a-b)/c) = (tan (A/2) - tan (B/2))/(tan (A/2) + tan (B/2)

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

i) In DeltaABC , if b=17, c=11 and angleA=60^(@) , find tan(B-C)/(2)

If in a DeltaABC, sin A, sin B, sin C are in A.P., show that 3 tan, A/2 tan, C/2 = 1

In triangle ABC, if |[1,1,1], [cot (A/2), cot(B/2), cot(C/2)], [tan(B/2)+tan(C/2), tan(C/2)+ tan(A/2), tan(A/2)+ tan(B/2)]| then the triangle must be (A) Equilateral (B) Isoceless (C) Right Angle (D) none of these
