The Attempt at a Solution
I see no way of doing this
You don't get magnification.… why do you get magnification apparent in this particuler case?
Sorry, this makes no senseThe only rays however that would form an image …
Yes, you obviously have the right idea now!2.2/10=x/310 ie I used similar triangles to work out how much of the image of the wall I could see. However, the answers use 300 as the distance from the mirror to the image of the wall and 2.5/10 instead of 2.2/10. (I just rooted the 5 to get the side length of the mirror). Have I made another mistake?
