Foundation June 2017 Paper 3 Q16
16 Triangles \(ABC\) and \(DEF\) are similar.
Not drawn accurately
(a) Work out the value of \(x\). [2 marks]
(b) Write down the size of angle \(y\). [1 mark]
| Answer | Mark | Comments |
|---|---|---|
| \(6 \div 3\) or 2 or \(9 \div 2\) or \(3 \div 6\) or 0.5 or \(9 \times 0.5\) or \(9 \div 6\) or 1.5 or \(3 \times 1.5\) or \(6 \div 9\) or \(\dfrac{2}{3}\) or \(3 \div \dfrac{2}{3}\) | M1 | oe |
| 4.5 | A1 | oe |
Additional guidance
| Accept embedded answer \(4.5 \times 2 = 9\) | M1A1 |
| Ignore further working in attempt to round after answer 4.5 eg \(9 \div 2 = 4.5\) with answer 5 | M1A1 |
| ‘The length is double’ without further working | M1A0 |
| ‘The triangle is double’ without further working | M0A0 |
