**Problem**

A 50-m steel tape that is is 0.02 m too long was used to measure the distance between two points *A* and *B*. If the measured distance was 160.42 m, calculate the correct distance between *A* and *B*.

A. 160.356 m | C. 160.844 m |

B. 160.484 m | D. 160.563 m |

**Problem**

The following interior angles (in degree) of a triangular traverse were measured with the same precision.

Angle | Value | No. of Measurement |
---|---|---|

A |
41 | 2 |

B |
77 | 6 |

C |
63 | 2 |

What is the most probable value of angle *C*, in degrees?

A. 62.423° | C. 62.571° |

B. 62.874° | D. 62.745° |
