If 2 mirrors are placed perpendicular to each other then infinite no of images will be formed because image formed by one mirror will act as the object for the other and vice verse.
Due to multiple reflection!

Use the formula [360/@]-1@ is the angle of inclination of the two mirrors.Suppose we keep the two mirrors in the same line, then @ = 180So there will be only one image.If suppose we keep two mirrors parallel to each other, then @ = 0 so infinite images.Now in your case @ = 45So 7 images will be seen.
Recursion is the process or act in which the person repeats its acts in a definite way. Like the images in two mirrors, kept par all to each other. There is a Never-Ending Image formed in both the mirrors.
Opposite each other
When a point P is placed between two perpendicular mirrors, the first image is formed by one mirror, and the second image is formed by the other mirror. The third image is the reflection of the second image on the first mirror. To locate the images, draw the path of light rays reflecting off each mirror. The images of P will appear symmetrically around the point of intersection of the two mirrors.
Virtual images.

If the mirrors are exactly parallel - there will be an infinite number of images, as they will be reflected indefinitely.
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.
To determine the number of images formed by a mirror, you need to consider the distance of the object from the mirror and the type of mirror (concave or convex). For a plane mirror, only one image is formed which is virtual and upright. For concave and convex mirrors, the number of images formed can vary depending on the position of the object relative to the focal point, center of curvature, and the mirror's surface.

When two mirrors are parallel to each other, an infinite number of images are formed due to the multiple reflections of an object between the mirrors. Each reflection creates a new image that is a mirror image of the previous one.
In theory, there should be infinitely many images. In practice, though, imperfections in the mirrors, diffusion in glass and the air gap between the mirrors mean that there are not infinitely many images.
With two mirrors at right angles you will have 3 (360/90 - 1) images of an object. Two of these are primary and the third is secondary. Some light rays from the object bounce of each of the mirrors to your eye to form the two primary images. But there are other rays that bounce off a mirror onto the second mirror before they get to you. This produced the secondary image.
