Here are the data collected by two geology students in their transect. You are to make a plot that shows the map view of their transect. The data were collected by measure the horizontal distance between two points and the bearing (angle measured in degrees from north) from the first to the second. Then they moved on to a new point and measure to it from the second point previously measured and so on.
Here is the location of their work:

Here are two maps of portions of the transect showing the points plotted along with the basic triangles that are needed ("de" is delta easting and "dn" is delta northing). You can check the math of your spreadsheet with them. The point numbers are labelled with their number and their coordinates in parentheses). Note how the coordinate is the cumulative de and dn.
