true
false

The answer is: FALSE:

Longitude can only be as high as 180°E ("180 degrees East");
or, 180°W ("180 degrees West").
   

False

Explanation:

The longitude refers to the geographical coordinates of the earth and it specifies the east-west position of a place on the surface of the earth. It could be as high as 210 degrees but it's never as the longitude of place in one direction of 210 degrees is not possible as its to reach about 180 degrees on another side.
