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 00.020 seconds)

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.
