To find out how many images are formed when plane mirrors are tilted at an angle, use the formula N=360/a-1 , wherein N is the number of images formed and a is the given angle. So in this case, N=360/30-1, will result to N=11 images formed.
2 images are formed
Three images will be formed when two mirrors are placed at a 60 degree angle. The multiple reflection of light rays creates these images due to the angle of reflection.

When two plane mirrors are tilted at an angle of 72 degrees, six images are formed. The first two images are the direct reflections from each mirror, and the remaining four images come from the multiple reflections between the mirrors.
When two plane mirrors are tilted at an angle of 60 degrees, there are 5 images will be formed.
The relationship between the number of images formed and the angle between two mirrors is described by the formula ( n = \frac{360^\circ}{\theta} - 1 ), where ( n ) is the number of images and ( \theta ) is the angle between the mirrors. As the angle decreases, the number of images increases, approaching infinity as the angle approaches zero. Conversely, larger angles result in fewer images. This phenomenon occurs due to the way light reflects between the mirrors, creating multiple images at various angles.
Virtual images.
a number of images that are formed if the object is placed between two mirrors at an angle. This is called multiple images.
