You are using extension ladders to paint a chimney that is 33 feet tall. The length of an extension ladder ranges in 1 foot intervals from its minimum length to its maximum length. For safety, you should always use an angle of about 75.5 degrees between the ladder and the ground. To reach the top of the chimney, your ladder will need to reach 30 feet up the wall. How many feet long will your extension ladder have to be? Write your answer to the nearest foot.
