Problema Solution
A person who is 5 feet tall is standing 120 feet from the base of a tree, and the tree casts a 130 foot shadow. The person's shadow is 10 feet in length. What is the height of the tree?
Answer provided by our tutors
let 'h' be the height of the tree
draw the tree, the person and the shadows - notice the similar triangles
the following proportion counts
h : 5 = 130 : 10
h = (5*130)/10
h = 65 feet
the tree is 65 feet high.
