For Latitude, the Equator is the zero point. For Longitude, the Prime Meridian at Greenwich UK, is the starting point of zero.
A longitude of 210 degrees means that you are measuring longitude from 0 to 360 degrees, which is fine, but very often people use -180 to +180 degrees, also called 180 degrees west to 180 degrees east instead. 210 degrees longitude is the same as 150 degrees west. You would pass French Polynesia and you would then make a landfall in Alaska in the USA which is in North America.
