4-83.

An airplane takes off and climbs at an angle of . If the plane must fly over a -foot tower with at least  feet of clearance, what is the minimum distance between the point where the plane leaves the ground and the base of the tower?  

  1. Draw and label a diagram for this situation.

  2. What is the minimum distance between the point where the plane leaves the ground and the tower? Explain completely

How can you use a slope ratio to find the minimum distance?

The slope ratio for  is .

A right triangle, hypotenuse labeled airplane take off, with arrow going up & right, horizontal leg labeled, x, angle opposite vertical leg labeled 11 degrees, vertical leg has 2 sections, lower labeled tower, 120 feet, upper labeled, 50 feet.
