|---|---|---|
| \(360 \div 8\) 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 |
