i don't know how to get the angle or the bearing lines

The angle should be the easiest because they give you 3 of the four angles and you know what the sum of all the angles in a four sided figure is 360 degrees right? You just need to convert the degrees and minutes to angles?

To find DA you need to create another triangle by dropping a line down from C to a point (E)to which you draw a line to the left until you hit D. That right triangle CED has one given angle DCE as 84 degrees 21 minutes. That allows you to find the angle CDE as 5 minutes and 39 minutes. Add this angle to 96 degrees and 11 minutes and doesn't that give you the Bearing of DA? Subtract 90 degrees and you would have the angle west of north.

The bearing of AB would then be (angle ADE)(180Angle DAB) and would be an angle rising north of the east bearing. If you have to convert to a north/south start you would subtract the angle from 90 and say East of North.

If it is then ignore what I wrote, I took it as west of south from the drawing. But I think it makes more sense that S angle W means going south a certain angle from west than starting from south going angle west.

its supposed to be ab, then bc, then da

Ok, if you want to start with AB, draw a line parallel to DC starting at point A

Find the angle between this new parallel line and AB and see how you would change the given bearing of CD with this new angle.

would i subtract ab from bc

Do you know these bearings? The problem gives you only 1 bearing and three internal angles. You need to construct the other bearings using the one that they give you and the internal angles as "adjustments" to find the other bearings. Also keep in mind that DC and CD are connected but not the same.
