The image above represents same meridian – same sides of the equator.

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

The formula for calculating same meridian – same sides of the equator:

θ = B – A

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 21 and the value of B is 30.

This implies that;

A = Value of A = 21

B = Value of B = 30

θ = B – A

θ = 30° – 21°

θ = 9°

Therefore, the **angular difference **is **9°.**

**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;

Find the value of B when the angular difference is 44 and the value of A is 5.

This implies that;

θ = Angular Difference = 44

A = Value of A = 5

B = θ + A

B = 44**°** + 5**°**

B = 49**°**

Therefore, the **value of B **is **49°.**
