The correct answer and explanation is :<\/strong><\/mark><\/p>\n\n\n\n
To calculate the Azimuth and Bearing of courses AB and BC in the given polygon, we need to follow a specific method based on the given information, which includes the azimuth of course CA being 344\u00b0.<\/p>\n\n\n\n
Step-by-Step Explanation:<\/h3>\n\n\n\n\n
Azimuth and Bearing<\/strong>:<\/li>\n<\/ol>\n\n\n\n
\n
Azimuth<\/strong>: This is the angle measured clockwise from the north (0\u00b0) to the line of travel. It ranges from 0\u00b0 to 360\u00b0.<\/li>\n\n\n\n
Bearing<\/strong>: A bearing is a direction expressed as a combination of degrees, starting from either north or south and then moving east or west.<\/li>\n<\/ul>\n\n\n\n\n
Course AB<\/strong>:<\/li>\n<\/ol>\n\n\n\n
\n
Given Point A is at 57\u00b0 and Point B is at 34\u00b0, this implies that the azimuth of course AB is the angle measured from point A to point B.<\/li>\n\n\n\n
The azimuth of course AB can be calculated by understanding that the azimuth of CA (344\u00b0) is given. The bearing from C to A is along course CA (344\u00b0), so if the angle between point C and point B is subtracted from the azimuth, we get the direction from A to B. Azimuth of AB<\/strong>: 57\u00b0.<\/li>\n<\/ul>\n\n\n\n\n
Course BC<\/strong>:<\/li>\n<\/ol>\n\n\n\n
\n
From Point B to Point C, the azimuth is given as 34\u00b0, which is also calculated using the given points and their relative positions.<\/li>\n\n\n\n
The Bearing from B to C is derived from this azimuth of course BC. Azimuth of BC<\/strong>: 34\u00b0.<\/li>\n<\/ul>\n\n\n\n\n
Converting to Bearings<\/strong>:<\/li>\n<\/ol>\n\n\n\n
\n
Bearing for AB<\/strong>: Since AB is in the range between 0\u00b0 and 90\u00b0, the bearing is North 57\u00b0 East<\/strong>.<\/li>\n\n\n\n
Bearing for BC<\/strong>: Similarly, for BC, as the azimuth is 34\u00b0, the bearing is North 34\u00b0 East<\/strong>.<\/li>\n<\/ul>\n\n\n\n
Result:<\/h3>\n\n\n\n
\n
Azimuth of course AB<\/strong>: 57\u00b0<\/li>\n\n\n\n
Bearing of course AB<\/strong>: North 57\u00b0 East<\/li>\n\n\n\n
Azimuth of course BC<\/strong>: 34\u00b0<\/li>\n\n\n\n
Bearing of course BC<\/strong>: North 34\u00b0 East<\/li>\n<\/ul>\n\n\n\n
Let’s illustrate the situation with a simple polygon plot.<\/p>\n\n\n\n<\/figure>\n\n\n\n
