Link traverse XP to TY, angles to right

Reading of the table: 148°15′ is the adjusted bearing of the known line XP and 36°45′ is the adjusted bearing of the known line TY. Angles are measured to the right at P, Q, R, S, T, so the bearing of the next line = bearing of the previous line + 180° + angle.

Rule (angles to the right): $\text{FB of next line} = \text{FB of previous line} + 180^\circ + \text{angle to the right}$ (add or subtract $360^\circ$ to bring the result between $0^\circ$ and $360^\circ$).

Step 1: Bearings computed from the observed angles

Computed FB of TY = 36°00′; given (observed) FB of TY = 36°45′.

Step 2: Angular misclosure

$$\text{Misclosure} = \text{given} - \text{computed} = 0^\circ 45'$$

The computed bearing of TY is 36°00′ against the known 36°45′: angular misclosure = +0°45′ (the computed bearing is 45′ less than the known one). It is distributed equally among the 5 angles (+9′ each).

Step 3: Adjustment

Total correction = +0°45′ (added to the computed bearing of the last line). It is distributed equally over the 5 observed angles: +0°45′ / 5 = +0°09′ per angle. The correction to a line is +0°09′ multiplied by the number of angles used to reach it.

Check: corrected FB of the last line equals the observed value 36°45′.

Answer: angular misclosure = +0°45′. Adjusted bearings: XP 148°15′, PQ 60°54′, QR 109°33′, RS 44°57′, ST 277°51′, TY 36°45′.
