Question

sum of a tan b tan c +b tan c tan a +c tan a tan b is equal to​

Answer 1

Answer:

We have to prove that tan A + tan B + tan C = tan A*tan B*tan C for any non-right angle triangle. For any triangle the sum of the angles is equal to 180 degrees. If we take a triangle ABC, A + B + C = 180 degrees.
