Question

a fence post casts a 4-foot shaddow at the same time that a tree next to it casts a 64-foot shaddow. how tall is the tree?

Answer 1

I think, since the sun's rays are parallel that all you can say is the tree is 16 times taller than the post.

But since you do not know the height of the post or the angle of the sun you cannot say the actual height.

Answer 2

thank u!
