Identify the latitude and longitude for each point from the diagram.

a) State the position of A, B, C, D in coordinate form (Lat, Long).

Step 1: Identify the latitude and longitude for each point from the diagram.

• Point A is at the intersection of $40^\circ N$ latitude and $30^\circ W$ longitude.
• Point B is at the intersection of $40^\circ N$ latitude and $20^\circ E$ longitude.
• Point C is at the intersection of $40^\circ S$ latitude and $20^\circ E$ longitude.
• Point D is at the intersection of $40^\circ S$ latitude and $30^\circ W$ longitude.

The positions are:
A: $\boxed{(40^\circ N
