Let's say we placed two plane mirror at an angle of 50°
For two mirrors kept at an angle x, the number of images n is determined by the formula 360/x.
If n turns out to be odd,We have the following two cases:Asymmetrically
--------------------
Number of images=nSymmetrically
------------------
Number of images=n-1And if n turns out to be even,Number of images= n-1 for all positions of object
Now, coming back to your question, Here x=50n=360/x  =360/50  =7.2Rounding off,n=7Now,n is odd.
(1) Asymmetricallynumber of images=n                             =7
(2) Symmetricallynumber of images= n-1                            = 7-1                            =6
