(a) Part of a regular polygon is shown.
Not drawn accurately
Assume that the polygon is an octagon.
Work out the size of angle \(x\). [2 marks]
(b) In fact, the polygon has more sides than an octagon.
What does this mean about the size of angle \(x\) ?
Tick one box. [1 mark]
- It is more than the answer to part (a)
- It is the same as the answer to part (a)
- It is less than the answer to part (a)
- It could be any of the above

|---|---|---|
| \(360 \div 8\) or 135 seen | M1 | oe eg \(45 \times 8 = 360\) or \(180 - \dfrac{(8 - 2) \times 180}{8}\) may be on diagram |
| 45 | A1 |
Additional guidance
| M1 may be awarded for correct work with no answer or incorrect answer, even if this is seen amongst multiple attempts | |
| 45 seen but not chosen as answer, even if linked to the wrong angle | M1A0 |
