.
In the given question, sound coming through the first pipe has angle of incidence equal to 40° that can be calculated as (90° - 50°)
The same sound will be reflected at an angle of 40°. Therefore, the second pipe has to be kept at the angle of 40° from normal.
Therefore the value of x will be 40°.
