These are similar triangles formed, which the illustration missing from the post, would show.
TREE
shadow on ground, 80 feet
height, unknown h.
VERTICAL ROD
shadow on ground, 4 feet
height, 6 feet
The two triangles, similar, would make a right angle where each object at the bottom meets its shadow.
