For azimuths between 0˚ and 90˚, use azimuth as shown in Figure 2-6.

For azimuths between 90˚ and 180˚, subtract azimuth from 180˚ (e.g.,
for 125˚ use 55˚).

For azimuths between 180˚ and 270˚, subtract 180˚ from azimuth
(e.g., for 205˚ use 25˚).

For azimuths between 270˚ and 360˚, subtract azimuth from 360˚
(e.g., for 295˚ use 65˚).
