@holy-cow Hell no! If we are dueling I'm using my chaining grips & plumb bob!!
They have these contests at the conference each year and from what I hear it's always won by the guy that gets lucky and sticks the tripod almost level on the initial flop.?ÿ ?????ÿ
Late to the party here, but perhaps the OP or others are still subscribed.
The drawing looks like a plat prepared for recording, but it has a sort of watermark reading "UNOFFICIAL COPY." There may well be an official copy out there with more information.
There's a heavy line, with easements on both sides of it, that looks like the line between Lots 3 and 4. But there's no bearing or distance on it. In any jurisdiction where plats are checked, that information would have been added before recording. There might also be chord bearings here and there.
Note that 158.84 + 33.54 = 192.22. 158.84 is not the length of the curve although it's labeled as if it is.
So, we're dealing with a curve with delta = 183 33 30, R = 60, and L = 192.22.
There are lines missing bearing & distance and some of the arc lengths are unclear from where to where?
If you enter all the brgs and distances, you can get a coord for both ends of that curve. Now we can calc in the rp, via dd int. And compare. It'll have the cumulative rounding error, but it will get us close enough, to go to the field...and get observations, and come up with something that would make a hand grenade smile!

On the south line there is a non-tangent curve with nothing to indicate its orientation. It might be tangent to some line that is outside of this drawing.
Bearing and distance are missing on the line between Lots 3 and 4 (marked below), plus there's a watermark saying "UNOFFICIAL COPY." Both those things suggest that this is not a final plat.
If the OP could come up with a final plat with complete geometry, there might well be enough information to compute the chord bearing he's looking for.

You are right. Multiple non tan curves are only good for.... Hmmmm dunno!

The delta for a diameter is 180?ø, the given delta of 183?ø33'30" is nearly a diameter and it's West of the center of the circle, not the typical curve diagram in textbooks. I get 119.94' as its length.
Complete the triangle from the SW tangent point to the NE corner (see diagram). In the low resolution of the map, it appears to go through the mark on the curve that shows the intersection of the easement and the curve. If that's true, then the angle of the constructed triangle at its SW point is 48.0234?ø.
The law of sines can be applied to find the azimuth of the chord.
Based on a big assumption that has to be verified in the field.
