**bobpursley**, Friday, July 30, 2010 at 6:17pmAre not there two similar triangles here..from the pinhole enveloping the monument on one side, from the pinhole enveloping the image on the other.

Using similarity,

5cm/167m=.2m/d

solve for d, the distance to the Monument.

I think I did this problem in the 8th grade, it is odd seeing it again.
