A person who is 6 feet tall walks away from flagpole toward the tip of the shadow of the flagpole. When the person is 30 feet from the flagpole, the tips of the person's shadow and the shadow cast by the flagpole coincide at a point 5 feet in front of the person. Find the height of the flagpole.
Draw a diagram to model the situation. Then, set up a proportion.
I probably going to need more to go on because if I knew how to do that (draw the model) I could have answered the problem already.
Your model is going to be two triangles. The larger triangle will be the flag pole, and inside that, you will have the person.
is it 42
