Use the angle fact that angles in a full turn add to 360°. To work the bearing, subtract 130° from 360°. 360° – 130° = 230° and so, the bearing of a from b is 230°.
How to Find Bearing?
Finding the bearing of a point, line, or surface is an important part of geometry and trigonometry. A bearing is a direction measured in degrees, usually in reference to the cardinal directions of North, South, East, and West. Knowing the bearing of a point can be useful in many different situations, such as when navigating with a map or compass, or when constructing a structure. In this article, we will discuss how to find the bearing of a point.
The first step to finding the bearing of a point is to measure the angle of the point relative to the cardinal directions. To do this, you can use a protractor, compass, or other measuring device. The angle should be measured from 0° to 360°, with 0° being north, 90° being east, 180° being south, and 270° being west.
Once you have the angle of the point, you can then calculate the bearing of the point. The bearing is the angle of the point in relation to a particular reference direction, usually north. To calculate the bearing, you will subtract the angle of the point from 360° and then divide by two. This will give you the bearing in degrees, with 0° being north, 90° being east,
