Q24 of 87 Page 10

In any triangle ABC, prove the following:

Let a, b, c be the sides of any triangle ABC. Then by applying the sine rule, we get



⇒ a = k sin A, b = k sin B, c = k sin C


So by considering the LHS of the given equation, we get



Substituting the corresponding values from sine rule, we get








Rearranging we get

















Regrouping this we get



But


Hence the above equation becomes,




(by applying sine rule)



Hence proved
