The sum of 43.9 and a number is 49.65, as shown below. What number should go in the box to complete the addition problem?

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

The answer is a. yes, it asks a question that can be answered correctly (by measuring hands).
