Finding Chord bearing
I need someone to explain to me how would I find the Choad bearing for this chart below
I know how to find the length, the chord, and the tangent but the chord bearing is throwing me off on the loop. does anyone have a formula they can provide?

Using trig functions you can find the angle - which will be half the angle of the total arc (the perpendicular of the chord to the arc center point is half the chord length). The rotation relative to the first road segment is 20 degrees counter clockwise so subtracting 20 degrees from 90 degrees leaves 70 degrees. Subsequent arcs use the previous chord angle as a reference.
