 Answer:
If TanA= x/(x+1) and TanB = 1/(2x+1) , Prove: A+B = π/4.

Since you need to prove the value of A+B and you have been given the values of tanA and tanB, it is obvious that you have to show the value correct using the formula of tan(A+B).

We know, π=180° and π/4 = 45°

So, first using the formula of tan(A+B), we find the value of tan(A+B).

These formulas might be helpful for you!



Then you need to compare both sides and cancel tan and then you get the values of A+B = 45° as shown in the image at the top!

Question: If TanA= x/(x+1) and TanB = 1/(2x+1) , Prove: A+B = π/4.

All the best!
