Then for angle AC?

Bearing of AB=152°30'
<ABC=124°28'
Bearing of BC=?
Back bearing of AB = BA = F.B + 180 = 152°30' + 180° = 332°30'
Bearing of bc = b.b of AB+<ABC = 332°30' + 124°28' = 456°58'
This is more than 360 so;
Bearing of BC = 456°58' - 360° = 96°58'.
<ABC=124°28'
Bearing of BC=?
Back bearing of AB = BA = F.B + 180 = 152°30' + 180° = 332°30'
Bearing of bc = b.b of AB+<ABC = 332°30' + 124°28' = 456°58'
This is more than 360 so;
Bearing of BC = 456°58' - 360° = 96°58'.

FB of AB=152°30'
BB of AB=152°30 ' +180° = 332°30'
FB of BC = BB of AB at B=332 °30' + 124°28' = 456°58'.
= 456°58' - 360° = 96°58'(remember if angle is more then 360° Subtract 360°).
BB of AB=152°30 ' +180° = 332°30'
FB of BC = BB of AB at B=332 °30' + 124°28' = 456°58'.
= 456°58' - 360° = 96°58'(remember if angle is more then 360° Subtract 360°).

Forward Bearing of AB =152°30'
Back Bearing of AB= 180°-152°30=27°30'
FB of BC= Included angle - BB of AB
=124°28'-27°30'
=96°58'.
Back Bearing of AB= 180°-152°30=27°30'
FB of BC= Included angle - BB of AB
=124°28'-27°30'
=96°58'.

Bearing of any line = BB.of line + angle.
If angle is more than 180' than, -360'.
You will find the answer.
If angle is more than 180' than, -360'.
You will find the answer.

152° 30'+ 180° = 332°30'.
360° - 332° 30' = 27° 30°.
Then do 124° 28' - 27° 30' = 96° 58'.
Hope you understand.
360° - 332° 30' = 27° 30°.
Then do 124° 28' - 27° 30' = 96° 58'.
Hope you understand.

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'.
