Textbook Question
Chapter 14.6, Problem 6P
A Thumb Sighting Problem: Suppose you are looking down a road and you see a person ahead of you. You hold out your arm and “sight“ the person with your thumb, finding that the person appears to be as tall as your thumb is long. Assume that your thumb is 2 inches long and that the distance from your sighting eye to your thumb is 22 inches. If the person is 5 feet 4 inches tall, then how far away are you from the person?
- Make a math drawing showing that the thumb sighting problem involves similar triangles. Explain why the triangles are similar.
- Solve the thumb sighting problem in two different ways. In both cases, explain the logic behind the method you use
