For Exercises 49 to 50, use the following information. Relative to its point departure or some other point of reference, the angle that is used to locate the position of a ship or airplane is called its bearing. The bearing may also be used to describe the direction in which the airplane or ship is moving. By using an angle between 0 ° and 90 ° , a bearing is measured from the North-South line toward the East or West. In the diagram, airplane A (which is 250 miles from Chicago’s O ’ Hare airport’s control tower) has a bearing of S 53 ° W. Find the bearing of airplane B relative to the control tower.

Figure in plane geometry formed by two rays or lines that share a common endpoint, called the vertex. The angle is measured in degrees using a protractor. The different types of angles are acute, obtuse, right, straight, and reflex.
A camera has been set up to record a diver at a diving competition. What is
important for those operating the camera is the viewing angle, which is the angle
made from the camera to the diver, called e in the picture below:
Diver
Sft
18 ft
Camera
Notice that the diver stands 8 ft tall with her arms extended, and the diving platform
is located 18 ft above the camera. The horizontal distance between the camera and
the diving board is called x.
If x = 12 ft, find the value of 0, rounded to the nearest tenth of a degree.
HINT: Notice there are two other angles, a and ß. Knowing these might help.
