How tall is a tree when matt is standing a hundred feet away looking uo at a 35 degree angle and his eyes are 5 feet from the ground

Question

A word problem I need help with. Matt wants to measure the height of a tree. He walks exactly 100 feet from the base of the tree and looks up. The angle from his eyes to the top of the tree is 35. If his eye level is 5 feet from the ground, what is the height of the tree? 

Answer 1

tan 35 = x/100 ---> x = 100 tan 35  is about 70

 

The tree is about 75 feet tall
