What Happens to Image Formation with Different Angles Between Plane Mirrors?

[physicolic]

As we know if the angle between two intersecting plane mirrors is 60 degrees 360/60 minus 1= 5 images of an object between the mirrors are formed. what will happen if the angle is 65 or 42,6 degrees?

Do you know WHY you get that result for 60 degrees?
(Draw a picture.)
