A plane mirror made of a very thin piece of glass lies flat on the ground. As shown in the following figure, one end of the mirror is 2.1 m from you and the other end is 35 m from a nearby tree. You are 1.6 m tall, and the mirror has a length L. The mirror is arranged so that you can just see the image of the top of the tree at one edge of the mirror. how tall is the tree?
I know you have to use the principle of similar triangles
The Attempt at a Solution
I tried using height of person/distance of person from mirror = height of tree/distance of tree from mirror . This is similar to a problem our TA did in class and I thought I was using the correct formula, however, I have been unable to get the correct answer and I dont understand what Im doing wrong and only have one attempt left for credit
