Transcribed Image Text:If Line AB is due North, the following are the interior angles the polygon ABCDE?
The following figure is not drawn to scale.
LINE
INTERIOR ANGLES
AB
ZEAB=118°30'
BC
ZABC=95°33'
B
CD
?
DE
ZCDE=134°10'
A
EA
ZDEA=140°50'
1. ZBCD =
50°57'
2. Exterior Angle at C = 309°03'
3. Deflection angle of line CD = 45°50' R
4. Angle to the right of line DE= 225°50'
5. Bearing of line BC = N 84°27'E
6. Azimuth from South of line BC = 264°27'
7. Back Azimuth from South of line BC = 84°27'
8. Azimuth from North of line CD = 213°30'
