# How to Calculate and Solve for Same Latitude – Different Sides of the Prime Meridian | Latitude and Longitude

**Last Updated on November 23, 2019**

The image above represents same latitude – different sides of the prime meridian.

To compute for same latitude – different sides of the prime meridian, two essential parameters are needed and these parameters are **value of A **and **value of B.**

The formula for calculating same latitude – different sides of the prime meridian:

θ = A + B

Where;

θ = angular difference

A = Value of A

B = Value of B

Let’s solve an example;

Find the angular difference when the value of A is 10 and the value of B is 12.

This implies that;

A = Value of A = 10

B = Value of B = 12

θ = A + B

θ = 10° + 12°

θ = 22°

Therefore, the **angular difference **is **22°.**

**Calculating the Value of A when the Angular Difference and the Value of B is Given.**

A = θ – B

Where;

A = Value of A

θ = angular difference

B = Value of B

Let’s solve an example;

Find the value of A when the angular difference is 32 and the value of B is 14.

This implies that;

θ = angular difference = 32

B = Value of B = 14

A = θ – B

A = 32° – 14°

A = 18°

Therefore, the **value of A **is **18°.**

**Calculating the Value of B when the Angular Difference and the Value of A is Given.**

B = θ – A

Where;

B = Value of B

θ = angular difference

A = Value of A

Let’s solve an example;

Given that the Angular difference is 50 and the value of A is 22. Find the value of B?

This implies that;

θ = angular difference = 50

A = Value of A = 22

B = θ – A

B = 50 – 22

B = 28

Therefore, the **value of B **is **28°.**
