" 4.In "/_ABC" with "sin((B+C)/(2))" in term "A/_A

In /_\ABC , sin((B+C)/(2)) = …………….

In Delta ABC , a sin ^(2) "" ( C ) /(2) + c sin ^(2) "" (A ) /(2) in terms of s,a,b,c is

In a Delta ABC " if " a^(2) sin (B - C) + b^(2) sin (C - A) + c^(2) sin (A - B) = 0 , then triangle is

In /_ABC,30A=6B=5C, then /_A=

In Delta ABC, if a sin^2""C/2+c sin^2""A/2 in terms of s,a,b,c is

In Delta ABC, if /_C=(/_A+/_B)/(2) then,find /_C

Assertion A:In/_ABC,sum(cos A)/(sin B sin C)=2 Reason R:In/_ABC,sin A+sin B+sin C=4(cos A)/(2)(cos B)/(2)(cos C)/(2)

If in a /_ABC(sin A+sin B)^(2)-sin^(2)C=3sin B sin C,then/_Cis

In a /_ABC if /_A=sin^(-1)((1)/(sqrt(5)))/_B=cos^(-1)((3)/(sqrt(10))) then
