Higher November 2021 Paper 2 Q6
6 Lines A, B, C, D and E intersect as shown.
Lines A and B are parallel.
Not drawn accurately
Work out the size of angle \(x\). [3 marks]
Using these letters for the unknown angles
| Answer | Mark | Comments |
|---|---|---|
| 73 | B3 | B2 \(180 - 110 + 52 - 49\) oe calculation or \(h = 107\) or \(j = 107\) or \(k = 73\) or \(g = 49\) and \(d = 58\) or \(g = 49\) and \(e = 70\) or \(f = 131\) and \(d = 58\) B1 any angle correct (others may be incorrect) |
Additional guidance
| Angles will usually be seen on the diagram | |
| Angles must be unambiguously linked to the correct position eg 131 seen in working but not on the diagram or in wrong position | B0 |
| \(a = 58 \quad b = 70 \quad c = 52 \quad d = 58 \quad e = 70\) \(f = 131 \quad g = 49 \quad h = 107 \quad j = 107 \quad k = 73\) \(m = 131 \quad n = 49 \quad p = 131 \quad q = 70 \quad r = 110\) \(s = 58 \quad t = 122 \quad u = 122\) |
