The formula for calculating the bearing AC from AB and angle A-C is: Bearing AC = Bearing AB + Angle A-C. This means that you add the bearing AB (measured clockwise from North) to the angle A-C (measured clockwise from the bearing AB) to get the bearing AC.
To convert the bearing AC from decimal degrees (ddd.dddd) to degrees, minutes, and seconds (ddd.mmss), you can use the following formula: Degrees = Int(Bearing AC), Minutes = Int((Bearing AC - Degrees) * 60), Seconds = (Bearing AC - Degrees - Minutes/60) * 3600. Note that the Int() function rounds down to the nearest integer.
Yes, this formula can be used for any type of bearings, as long as the bearings are measured clockwise from North and the angles are measured clockwise from the bearing AB. This formula is commonly used in navigation and surveying.
The angle A-C should be in decimal degrees (ddd.dddd). If the angle is given in degrees, minutes, and seconds, you can convert it to decimal degrees by dividing the minutes by 60 and adding the result to the degrees, and then dividing the seconds by 3600 and adding the result to the previous result.
This formula is accurate as long as the measurements of the bearing AB and angle A-C are accurate. Small measurement errors can result in slight differences in the calculated bearing AC. It is important to use precise instruments and make accurate measurements for the most accurate results.
