(a) tan A+tan B+tan C=tan A tan B tan C

Given that A = B +C. prove that tan A - tan B - tan C = tan A tan B tan C.

If A + B + C =180^@ , prove that : tan A + tan B + tan C = tan A tan B tan C .

If A + B + C = 180^(@) , then prove that tan A + tan B + tan C = tan A tan B tan C.

If A + B + C = pi , prove that tan A+ tan B + tan C = tan A tan B tan C

If A + B + C = 180^(@) , then prove that tan A + tan B + tan C = tan A tan B tan C.
