Get stick long as your arm, extent arm holding stick horizontally, walk back until top of tree and top stick align(45 degrees). You now have a isosceles triangle and the distance between you and the tree is the same as the height of the tree.
So you never showed me how to figure out the height of the tree that’s the whole reason I watched the video. This is video number seven. I’ve watched now and still no one has showed me how to measure the height of a tree. It’s a simple request how tall is my tree, I know the distance I know the angle to the top how tall is my tree? I’m 2 m tall
