Bearing of AB=152°30'.
Angle ABC = 124°28'.
Bearing BC=?
Bearing BA = AB + 180 = 152°30'+180°= 332°30'.
Bearing BC= AB + angle ABC = 332°30' + 124°28' = 456°58'.
Then 456°58'-360°= 96°58'.
Angle ABC = 124°28'.
Bearing BC=?
Bearing BA = AB + 180 = 152°30'+180°= 332°30'.
Bearing BC= AB + angle ABC = 332°30' + 124°28' = 456°58'.
Then 456°58'-360°= 96°58'.

FB of BC = FB of AB+<ABC+-180.
= 152 * 30' + 124 * 28'-180° (first two values sum is more than 180 so use -ve sign).
= 276 * 58'-180° = 96° 58'.
= 152 * 30' + 124 * 28'-180° (first two values sum is more than 180 so use -ve sign).
= 276 * 58'-180° = 96° 58'.

Fore bearing BC = back bearing AB + clockwise Angle ±180° ±540°.
BC = 152°30'+124°28'±180°±540°.
BC = 276°58'-180°.
BC = 96°58'.
Fore bearing BC=96°58' answer.
BC = 152°30'+124°28'±180°±540°.
BC = 276°58'-180°.
BC = 96°58'.
Fore bearing BC=96°58' answer.

Bearing of AB =152°30'.
Angle ABC = 124°28'.
Bearing BC = ?
Bearing BA = AB + 180 = 152°30' + 180°= 332°30'.
Bearing BC = AB + angle ABC = 332°30' + 124°28' = 456°58'.
Then 456°58' - 360° = 96°58'.
Angle ABC = 124°28'.
Bearing BC = ?
Bearing BA = AB + 180 = 152°30' + 180°= 332°30'.
Bearing BC = AB + angle ABC = 332°30' + 124°28' = 456°58'.
Then 456°58' - 360° = 96°58'.

Bearing of AB = 152° 30'
Angle at B = 124° 28'
The bearing of BC=?
Back bearing= forward bearing + included angle,
CB=152 30' + 124 28'= 276 58`.
Since we asked to find the forward bearing i.e BC,
BC= 276 58` - 180 = 96 58'.
Angle at B = 124° 28'
The bearing of BC=?
Back bearing= forward bearing + included angle,
CB=152 30' + 124 28'= 276 58`.
Since we asked to find the forward bearing i.e BC,
BC= 276 58` - 180 = 96 58'.

Sum = WCB of AB + ∠B.
If Sum < 180° → WCB of BC = Sum + 180°.
If Sum ≥ 180° → WCB of BC = Sum - 180°.
If Sum ≥ 540° → WCB of BC = Sum - 540°.
If Sum < 180° → WCB of BC = Sum + 180°.
If Sum ≥ 180° → WCB of BC = Sum - 180°.
If Sum ≥ 540° → WCB of BC = Sum - 540°.
