If the angle between two plane mirrors is 60 degrees, then what is the number of images made of an object situated in between the mirrors? What does Google know about me? There will be 5 images formed. You have use the formula (360/angle) - 1, if 360/angle is even, otherwise you'll have to use 360/angle..
