If `A=sqrt((s-a)(s-b)(s-c))`, then express c in terms of A,s,a and b.

(a) Solve the equation sqrt(6-4x-x^2)=x+4 OR (b) Prove that in any DeltaABC,Delta=sqrt(((s-a)(s-b))/(s(s-c))) , where s is the semi - perimeter of DeltaABC ?

In Heron's formula , area of triangle =sqrt(s(s-a)(s-b)(s-c)), s is …………………..of the triangle.

If, in triangleABC, (s-a)(s-b)=s(s-c) , then: angleC =

If c^(2) = a^(2) + b^(2) then write the value of 4s ( s- a) (s-b) (s-c) in terms of a,b.

If a/(sinA)=K , then the area of "DeltaA B C" in terms of K and sines of the angles is (K^2)/4s in A\ s in B\ s in C (b) (K^2)/2s in A\ s in B\ s in C 2K^2s in A\ s in B\ "sin"(A+B) (d) none

If (s-a) +(s-b) +(s-c) =s , then the vlaue of ((s-a)^(2) +(s-b)^(2) +(s-c)^(2) +s^(2))/(a^(2) +b^(2)+c^(2)) will be

In a triangleABC , sqrt[{(s-a)(s-b)}/{s(s-c)}] is:
