| Answer | Mark | Mark scheme |
|---|---|---|
| 132 | M1 | for finding an exterior angle eg \(360 \div 6\ (= 60)\) or \(360 \div 5\ (= 72)\) or an interior angle eg \(180 \times 4 \div 6\ (= 120)\) or \(180 \times 3 \div 5\ (= 108)\) |
| M1 | for a complete method eg \(360 - \text{``}120\text{''} - \text{``}108\text{''}\) or \(\text{``}60\text{''} + \text{``}72\text{''}\) | |
| A1 | cao |
