Locate point C in grid square 3050 above, using the coordinate scale on your
protractor and the following procedures:
o Place the proper coordinate scale of your protractor on the map so the
zero-zero point is to the BOTTOM RIGHT of the scale as shown in figure
below
o Place the zero-zero point at the lower left-hand corner of grid square 3050
as shown in figure below.
o Keep the horizontal line of the scale directly on top of the east-west grid
line (in this case, grid line 50) and slide it to the right until the vertical line
of the scale touches the point C for which the coordinates are desired as
shown in figure below.
