Answer 2

Answer:

13. (iii), 14. (ii), 15. (iv), 16. (i), 17. (iii)

Step-by-step explanation:

13. (iii) is the correct. Because, if we take two angles adjacent as, ∠ABC and ∠BCD. We have BC as a common arm, B as a common vertex, but no common interior.

14. (ii) is correct. Because ∠1 + ∠2 = 180°

15. (iv) is correct. Because, Vertically Opposite Angles are equal

16. (i) is correct. Because, if we construct an angle all around a point, we get 360°

17. (iii) is correct. Because, according to Linear Pair, ∠COD + ∠BOC + ∠BOA = 180°

So, by substituting the values of ∠COD and ∠BOA. We get,

65 + 30 + ∠BOC = 180

∠BOC = 180 - 100

∠BOC  = 80°
