1. A helicopter is at a position from two VORS (VHF Omnidirectional Radio Range, an aircraft navigation system operating in the VHF band -
not covered in chapter) as in the diagram shown below. Given the angles
shown, find the third angle.
Helicopter
74.0°
66.0°
VOR
VOR

The position of the helicopter and the two VORs forms a triangle and the third angle formed by these three entities is 40 degrees

The diagram is not shown; however, the question can still be answered.

The given angles are:

Represent the third angle as

The helicopter and the 2 VORs form a triangle.

So, we make use of the following theorem to calculate the third angle

---- sum of angles in a triangle

Substitute known values

Collect like terms

Hence, the third angle is 40 degrees.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
