From his viewpoint, Larry estimates that there is a 25° angle to the top of his house. At the same time, he estimates that there is a 65° angle to the top of a nearby 83-foot tree. What is the height of Larry's house?

b, i believe, but not sure.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
