Can a real image be formed by a convex mirror?

An object is placed at a distance of 25 cm from a convex mirror. A plane mirror is placed such that the two images formed by the two mirrors are in the same plane. The distance of the plane mirror from the object at this position is 20 cm. Calculate the radius of the convex mirror.
