Question

1. AZ|AB = 272° 09’ 15”
2. BRG|BC = S 16° 13’ 51” W      
3. AZ|CD = 96° 52’ 00”
4. BRG|DA = N 7° 42’ 35” W

2. you were given directions (bearings or azimuths) of 4 sides of a closed polygon traverse: ABCDA.
   1. By taking the difference between successive azimuths, find the four deflection angles (i.e., angles from the projection of the previous line to the next line) for this traverse. For example: DEFL ∠B = AZ|BC – AZ|AB. What is the sum of the deflection angles?
   2. For this traverse, what is the geometrically correct total of the sum of the interior angles ((INT ∠))?
   3. For this traverse, what is the geometrically correct total of the sum of the exterior angles ((EXT ∠))?
