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
⇒c = k sin C
Similarly, b = k sin B
And a = k sin A
Here we will consider LHS, so we get
Substituting corresponding values in the above equation, we get
But,
Substituting the above values in equation (ii), we get
Hence proved
