Any airways at all from this VOR? Use your protractor to measure the
angle
between the radial defining the charted airway and the line you just drew.

Or even better, just drop the plotter on top of the existing airways and
line up the appropriate degree markings with the airways. Then just read
the magnetic course from the drawn course line underneath the plotter. No
need to measure any angles at all.

This will be better than applying the local variation, since VOR radials are
not kept 100% up-to-date with changes in variation. Using existing airway
headings will ensure that the drawn course matches the radio indication,
even if not the magnetic compass.
