Question

An observer for a radar station is located at the origin of a coordinate system. For the point given, find the bearing of an airplane located at that point. Express the bearing using both methods.(-8,0)

Answer 1

Given,

The coordinates of the point is (-8, 0).

There are two methods of bearing is:

Compass bearing

True bearing.

The figure of the point is,

The bearing of the point with respect to anticlockwise from north is,

`\begin{gathered} \tan \theta=(y)/(x) \\ \tan \theta=(0)/(-8) \\ \theta=\tan ^(-1)0 \\ \theta=0^(\circ) \\ \text{Bearing from north=(90}^(\circ)-0^(\circ))=90^(\circ) \end{gathered}`

The bearing of point from west is 0 degree and from anticlockwise north is 90 degree.

The true bearing is,

`\begin{gathered} \theta=0^(\circ) \\ B=(360^(\circ)-90^(\circ)) \\ B=270^(\circ) \end{gathered}`
