How you get this answer can you explain the procedure for this? |

Back bearing of ab line is 332 degree 30 min. Therefore angle reduced bearing with north is 360 minus above bearing which is 27 degrees 30 min. Then subtract this from above angle that is 124 degree 28 min minus 27 degree 30 min gives you answer. |

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'. |

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

Thanks a lot for explaining @Mr Salim. |

I am not getting the solution. Please, anyone explain me. |

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

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'. |

Best Explanation, Thanks @Julliet Osunde. |

Burhan Ali said: (Aug 24, 2020) | |

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°). |

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'. |

Then for angle AC? |

Manvi said: (Sep 19, 2020) | |

Please explain, how to calculate the angle AC? |

Prashanth said: (Jan 10, 2021) | |

For anticlockwise how to measure it? |
