if A and B are acute angles such that tan A= 1/3 , tan B = 1/2 and tan( A +B) = (tan A+ tanB) /(1- tanA tanB), show that A+ B = 45°.

This is the basic and conceptual question from trigonometric ratios in which we have given A and B are acute angles such that tan A= 1/3 , tan B = 1/2 and tan( A +B) = tan A+ tanB / 1- tanA tanB

We have to prove  that A+ B = 45°

RS Aggarwal, class 10, chapter 11, question no 16.
