A surveyor is measuring a triangular lot. From point A he measures 400 m at a bearing of N20°E to reach point B. He then adjusts his equipment to read S60°E for 600 m until
he reaches point C. How far is point C from point A? Finish labelling the diagram, then
show all steps in your solution. [4A, 2C

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
