Answer:
Explanation:
The number of images formed when two mirrors are placed at an angle theta to each other is given by: n = ( 360 / theta ) - 1.
Here, n = 5, so ( 360 / theta ) = n+1 = 6, hence theta = 360/6 = 60 deg.
So the mirrors are placed at an angle of 60 deg with each other.

Explanation:
let the required angle be x
then, the numbers of images formed by the mirror
=(360°/x)-1
=>5=(360°/x)-1
=>6=360°/x
=>x=60°
