1. The problem states that ship C is 45 km from ship B on a bearing of 124°. 2. Since the scale is 1 cm to 6 km, first convert 45 km to the scale length: $$\text{Length on scale} = \frac{45}{6} = 7.5 \text{ cm}$$ 3. To plot ship C from ship B on the scale diagram, measure 7.5 cm from B at an angle of 124° clockwise from North. 4. Because bearings are measured clockwise from North, draw a line from point B directed at 124°, then mark ship C at 7.5 cm along this line. 5. For part (ii) about drawing a chord of the circle: a chord is a straight line connecting two points on the circle. Draw any straight line inside the circle that touches the circumference at two points. Final answers: - Ship C is plotted 7.5 cm from B on a 124° bearing. - Draw a chord by connecting two points on the circle.
