Question

Yadi (1+tanx) (1+tany) = 2 ho to x+y hoga

Answer 1

15 thanks + follow = 16 thanks + follow back.This is my promise.

Answer 2

Answer:

x+y= π/4

Step-by-step explanation:

(1+tanx)(1+tany)=2

1+tany +tanx +tanx*tany=2

tanx+tany=1+tanx*tany

tanx+tany/1+tanx*tany=1

tan(x+y)=1

x+y= π/4
