What point on the diagram correctly locates 15 degrees and 30 degrees w?

To accurately locate 15 degrees and 30 degrees on a diagram, you would typically refer to a circular diagram or protractor. For 15 degrees, you would find the point slightly to the right of the 0-degree line, while 30 degrees would be further along the same line, positioned between 0 and 45 degrees. Both points should be marked clearly to indicate their respective angles from the horizontal baseline.
