Answer:

The formula for number of images formed by two plane mirrors placed at certain angle is (360/n). n is the angle.

just remember that the number of images formed must be ODD numbers.

if the result is even then you need to subtract 1 from that.

if it is odd u need not subtract , since the number of images ever formed are only odd.

using the formula 360/n where n is the angle

for 180 degrees

360/180 = 2 - 1 = 1 images

for 120 degrees

360/120 = 3 images

for 90 degrees

360/90 = 4-1 = 3 images

for 60 degrees

360/60 = 6 - 1 = 5 images

45 degrees

360/45 = 8 - 1 = 7 images
