Foundation November 2021 Paper 2 Q16
16 \(AB\) is parallel to \(CD\).
\(FG\) is a straight line.
Not drawn accurately
Work out the size of angle \(x\). [3 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(x + 53 + 48 = 180\) or \(53 + 48\) or 101 or \(180 - 53\) or 127 or any correct angle marked as 53 or 127 on the diagram | M1 | oe equation in \(x\) |
| \(180 - (53 + 48)\) or \(360 - 53 - 53 - (180 - 53) - 48\) | M1dep | oe eg \(180 - 101\) or \(127 - 48\) |
| 79 | A1 |
Additional guidance
| M1 may be awarded for correct work, with no or incorrect answer, even if this is seen amongst multiple attempts | |
| Correct angle on diagram may be credited even if alongside other incorrectly marked angles or incorrect or no working in working lines | |
| Correct method in the working lines may be credited even with incorrect angles on the diagram | |
| Method for 79 followed by further work to their 79 | M1M1A0 |
