You can use a formula

#360/theta - 1 # will be the number of images formed (#theta# is the angle between 2 mirrors

so lets call #theta#, x

hence

#360 /x - 1 = 5#

solving for #x# you will get #60# degrees

now add 30 degrees to it so rewrite the equation as :

#360/90 - 1 = y #

solving for # y # you will get 3 as the answer

Hope you understood (P.S if this is your hw problem please learn from the videos and not from the answers given )
