    1. 83 (540 - 110 -105 - 112 - 130) 2. 120 (All sides are equal, regular polygon. 6x180 = 1080. Sum of exterior angles = 360. 1080 - 360 = 720. 720/6 sides = 120) 3. 72 (I am thinking it is an error from tutor and its a regular polygon. If so, follow above method) 4. 165 (Angle inside polygon = 135 as it is regular polygon. Equilateral triangle is formed outside, so 60 deg. 135 + 60 = 195. And complete circle angle is 360. So, 360 - 195 = ?) 5. 130 (Angle inside polygon is 360 - 130 - 90 - 90 = 50. ? forms straight angle with 50 deg angle of polygon. so, 180-50 = ?) 6. 45 (5 angles = 540 internal sum. ? = 540 - 220 - 105 - 105 - 65) 7. 135 (45 from previous. 180 - 45 = 135) 8. 315 (45 from previous. 360 - 45 gives rest of full angle) Please correct me if I am wrong.
