Both maps below show Angola highlighted. At 12° Mercator inflates Angola by only about 5%, so the two maps largely agree on it. Watch what the old map does to Namibia beside it. That contrast is why the new world map matters.
At 12°, Angola sits in the band the old map drew almost honestly. It is one of the regions Mercator quietly under-represented, and that is exactly what the new Equal Earth map restores.

Old maps drew Angola at about 1,305,669 km². The truth is 1,246,700 km², a difference of 5% that school atlases carried for centuries.
