True Bearing if Declination is in West Solution

STEP 0: Pre-Calculation Summary

Formula Used

True Bearing = Magnetic Bearing-Magnetic Declination
TB = MB-MD
This formula uses 3 Variables

Variables Used

True Bearing - (Measured in Radian) - True Bearing is the horizontal angle measured clockwise between the true meridian and the line is called true bearing of the line.
Magnetic Bearing - (Measured in Radian) - Magnetic Bearing is the horizontal angle which a line makes with the magnetic meridian is called magnetic bearing. It varies with time.
Magnetic Declination - (Measured in Radian) - Magnetic Declination is the horizontal angle between true north and magnetic north at the time of observation.

STEP 1: Convert Input(s) to Base Unit

Magnetic Bearing: 55 Degree --> 0.959931088596701 Radian (Check conversion here)
Magnetic Declination: 5 Degree --> 0.0872664625997001 Radian (Check conversion here)

STEP 2: Evaluate Formula

Substituting Input Values in Formula

TB = MB-MD --> 0.959931088596701-0.0872664625997001

Evaluating ... ...

TB = 0.872664625997001

STEP 3: Convert Result to Output's Unit

0.872664625997001 Radian -->50 Degree (Check conversion here)

FINAL ANSWER

50 Degree <-- True Bearing

(Calculation completed in 00.004 seconds)

Included Angle when Bearings are Measured in Same Side of Different Meridian

Go Included Angle = (180*pi/180)-(Fore Bearing of Previous Line+Back Bearing of Previous Line)

Included Angle when Bearings are Measured in Opposite Side of Common Meridian

Go Included Angle = Back Bearing of Previous Line+Fore Bearing of Previous Line

Included Angle from Two Lines

Go Included Angle = Fore Bearing of Previous Line-Back Bearing of Previous Line

Magnetic Bearing given True Bearing with East Declination

Go Magnetic Bearing = True Bearing-Magnetic Declination

Magnetic Bearing given True Bearing with West Declination

Go Magnetic Bearing = True Bearing+Magnetic Declination

True Bearing if Declination is in East

Go True Bearing = Magnetic Bearing+Magnetic Declination

True Bearing if Declination is in West

Go True Bearing = Magnetic Bearing-Magnetic Declination

Magnetic Declination to East

Go Magnetic Declination = True Bearing-Magnetic Bearing

Magnetic Declination to West

Go Magnetic Declination = Magnetic Bearing-True Bearing

Fore Bearing in Whole Circle Bearing System

Go Fore Bearing = (Back Bearing-(180*pi/180))

True Bearing if Declination is in West Formula

True Bearing = Magnetic Bearing-Magnetic Declination
TB = MB-MD

What is a True Meridian?

The true meridian passing through a point on the earth’s surface is the line in which a plane passing through the given point and the geographic (true) north and south poles, intersects the surface of the earth. The direction of true meridian at a station is invariable, i.e., its direction is always the same.

What is a True Bearing?

A True Bearing is the horizontal angle between the direction of an object and true north, measured in degrees clockwise.

How to Calculate True Bearing if Declination is in West?
