20 The diagram shows triangle ABC.
Not to scale
AC = 12 cm, angle CAB = 40° and angle ABC = 58°.
Calculate length BC. [3]
| Answer | Marks | Part marks and guidance | |
|---|---|---|---|
| 9.09 to 9.1 | 3 | M2 for [BC =] \(\frac{12 \times \sin 40}{\sin 58}\) oe or M1 for \(\frac{12}{\sin 58} = \frac{\text{BC}}{\sin 40}\) oe | Allow any complete and correct alternative method |
