I would check out the Traverse tool in the Modify Features toolbox. Makes it very easy to draw up most parcel descriptions. They way that text reads, I would assume it's a deflected angle, but it's not clear if that's meant to deflect from the previous segment (a "lookback" deflection) or from the prolongation of the previous segment.
In other words, is it "create a 145 degree angle from the last course" or "turn 145 degrees". But the nice thing is that the Traverse tool allows you to update the entered bearings and distances to see the entire shape adjust accordingly.
