what countries does the 30 degree line of longitude pass through from the north pole to the south pole
The Tropic of Capricorn passes through South America, Africa, and Australia.
The international dateline passes through the Pacific Ocean. The international dateline is an imaginary line that is 180 degrees east of the Greenwich Meridian.
The 'parallels' of latitude are numbered in degrees north or south of the equator, from zero to 90 degrees. The equator is zero; the poles are 90 degrees north/south. The meridians of longitude all pass through the poles. They're numbered in degrees east or west of the Prime Meridian, from zero to 180 degrees. The Prime Meridian ... the line defined as zero longitude ... is the meridian that joins the north and south poles and passes through Greenwich, England. (That's the origin of the terms "near east", "middle east", and "far east" ... they're the regions that are near, medium, and far to the east, beginning in England at the prime meridian.)

Well, this is a very close estimate so I would say about 42 degrees East to about 47 degrees East.
The Prime Meridian crosses the continents of Europe, Africa, and Antarctica. The Prime Meridian is the 'zero' dividing line between east and west, so it has neither of those labels.
The Antarctic Circle does not pass through any country.
No. The points on the border of Malawi that are closest to the Prime Meridian are about 32.9 degrees east of it.
the prime meridian passes through continents
The continent that the equator does not pass through is Europe, North America, Australia, and Antarctica.
Three of them.
North America
