90°E, 170°W, 30°E, 20°W

Answer 1

• 90°E – 90°W
• 170°W – 10°E
• 30°E – 150°W
• 20°W – 160°E

• The meridians are located on opposite sides of the globe, each 180° apart.
• The East and West meridians mirror each other. For example, 90°E is opposite to 90°W.
• These pairs of meridians divide the globe into two hemispheres: the Eastern Hemisphere and the Western Hemisphere.
