A field is in the form of a regular pentagon. It is required to determine the directions of
bounding sides. The magnetic declination of the locality is 05°30' west. If the magnetic azimuth
reckoned from south of side AB is 33º20', determine the true azimuths reckoned from north of
the following sides of the field: AB, BC, CD, DE, and EA. Assume that the corners are labelled in
a clockwise direction.
