That (screenshot) is where you need to make the changes. you use degrees for angle and set yoru precision to second or decimal seconds dependong on your calls. 90d45'36.05".
Select whether you want clockwise or counter with the checkbox in your screenshot.
Then in the direction you set the north direction.
As described here on dotsoft.com...
How do I enter boundaries in bearing & distance?
First you need to set the appropriate units in the DDUNITS command. Set the angular units to 'Surveyor', then choose the direction button and make sure that 'Angle Direction' = east, 'Rotation' = counter clockwise. Even though you have set to Surveyors Units it won't work right unless set this way.
Then using the LINE or PLINE command you enter the calls as relative polar coordinates.
Start Point: (Pick One)
Next Point: @123.45 < N45D30'15"E
Next Point: @234.56 < S25D10'10"W
Notice the syntax for the relative polar coordinate. You put the @ sign first, which means relative to the last point. Next comes the distance. Last is the bearing. Its enclosed in the quadrant NE, NW, SE, SW, note the use of letter D to indicate the degrees.
