| (Angle EBC = 180 – 112 = ) 68 (°) | B1 | Check diagram for answers. |
| (Angle BED or Angle AED =) 360 – (123 + 110 + 68) or equivalent | M1 | Award M1 for complete method to find Angle BED or intention of complete method provided not contradicted e.g. 360 – 123 + 110 + 68 with 123 + 110 + 68 added incorrectly but attempt to subtract from 360. FT 360 – (123 + 110 + ‘their 68’), provided ‘their 68’:
