The question, in short
Using a right-angled triangle PQR with the right angle at Q, side PQ = 6.5 cm and angle PRQ = 24°, calculate QR to 3 significant figures.
Summarised in our own words. Use the official paper for the exact wording and the diagram.
Solution · 3 marks
- 1tan 24° = 6.5/QR
- 2QR = 6.5/tan 24°
- 3QR = 14.599...
- 4QR = 14.6 cm (3 sf)
