If `cot(A/2)=(b+c)/a` then `Delta ABC` is

If in triangle ABC,cot(A/2)=(b+c)/a, then the triangleABC is

In triangle ABC, if (cot A)/(2)=(b+c)/(a), then triangle ABC must be

IF Delta ABC, if cot""A/2=(b+c)/a , then the triangle is

In Delta ABC If cot A+cot B+cot C=sqrt(3) then Delta ABC is

In Delta ABC if cot A+cot B+cot C=sqrt(3) then Delta ABC is

If A,B ,C are the angle of Delta ABC then cot A .cot B + cot B . "" cot C + cot C.cot A =

In triangle ABC, if cot A*cot C=(1)/(2)andcot B*cot C=(1)/(18) then the value of tan C is

In ABC,(cot A)/(2)+(cot B)/(2)+(cot C)/(2) is equal to (Delta)/(r^(2))(b)((a+b+c)^(2))/(abc)2R(c)(Delta)/(r)(d)(Delta)/(Rr)
