Q1) Balance the following interior angles (angles to the right) of a five- sided closed polygon
A track of land has 3 straight boundaries AB, BC, and CD, the fourth boundary DA is
irregular, and the measured length are as under:
traverse. If the azimuth of side AB is fixed at 74° 31'17" calculate the azimuth of the
remaining sides
AB =135m
BC= 191m
CD= 126m
BD= 225m
A= 105° 13'14", B = 92° 36 06", C=67° 15 22", D=217° 24'30" and E= 57° 30'38
The offsets measure outside the boundary DA to the irregular boundary at a regular
interval of 30m from D are as belilow
