To isolate an enclosed area for conservation, an open traverse is run keeping close to (but outside of) the exterior boundary of the area through ground points A → B → C → D → E → F → G → towards H (to be eventually located). AB is 80° to the East of the North line at A. Deflection / Interior angles at B, C, D, E, F are indicated. What would be the magnitude of the deflection angle at G (as marked) so that GH may run parallel to BA? (Lengths are immaterial in this case.)

Sum of internal angles of polygon,

∑I = (n - 2) × 180° 

∑I = (8 - 2) × 180° = 1080° 

∠A + ∠B + ∠C + ∠D + ∠E + ∠F + ∠G + ∠H = 1080° 

100° + 230° + 80° + 270° + 60° + 70° + ∠G + 80° = 1080° 

∴ ∠G = 190°

Gaurav cycles towards South-West for a distance of 6 m and stops there. Further, he moves towards East a distance of 10 m and from there he moves towards North-East a distance of 6 m. Next, he moves towards West a distance of 6 m. Now, he moves towards North-West a distance of 2 m. Next, he moves towards West a distance of 4 m and then towards South-West 6 m and stops at that point. Now, where is he from the starting point?
