The question, in short
Using the given parallel-line diagram with 59° and 37° marked, work out the sizes of angles a, b and c.
Summarised in our own words. Use the official paper for the exact wording and the diagram.
Solution · 3 marks
- 1a = 59 (vertically opposite angles)
- 2b = 37 (corresponding angles, parallel lines)
- 3c = 180 − 59 − 37 = 84 (angles in a triangle)
- 4a = 59, b = 37, c = 84
Answera = 59, b = 37, c = 84
