An airplane is approaching Los Angeles International Airport at an altitude of 10,560 feet. If the horizontal distance from the plane to the runway is 2.1 miles, use the Pythagorean Theorem to find the diagonal distance from the plane to the runway (see the figure below). (5,280 feet equals 1 mile.)

The observation deck of the Skylon Tower in Niagra Falls is 166m above the river. Two boats are in the river with passengers looking up at the tower. -Boat A is 60 degrees south of east with an angle of elevation of 50 degrees -Boat B is 130 degrees south of east with an angle of elevation of 56 degrees Calculate the distance between the two boats. Include a diagram for full marks.

A plane starts to take off from the beginning of the runway. When the plane is level with the end of the runway, it is 500 feet above the ground. A bird is flying in the same direction. It is 8 feet above the ground and 15 feet from the begining of the runway. How far is the plane from the beginning of the runway?
