21. Answer: 8 lines of symmetry A regular octagon has 8 lines of symmetry.

22. Answer: 108° Angles on a straight line = 180° Other angle = 180° - 72° = 108°

23. Answer: 15.0 or 15 12.5 + 8.75 - 6.25 = 21.25 - 6.25 = 15.00

24. Answer: 120° From 12 to 4 is 4 hours. Hour hand moves 30° per hour. 4 × 30° = 120°

25. Answer: 3.09 18.54 ÷ 6 = 3.09

Section C: Word Problems (25 marks)

26. Answer: 15.23 kg

Working: Total weight = 8.45 + 6.78 = 15.23 kg

27. Answer: $46.75

Working: Money left = $92.50 -$ 45.75 = $46.75

28. Answer: 3.9 m

Working: Length of each piece = 27.3 ÷ 7 = 3.9 m

29. Answer: 31.05 kg

Working: Total weight = 3.45 × 9 = 31.05 kg

30. Answer: x = 48°, Acute triangle

Working:

Sum of angles in triangle = 180°
x + 58 + 74 = 180
x + 132 = 180
x = 180 - 132 = 48°

All angles (48°, 58°, 74°) are less than 90°, so this is an acute triangle.
