Van was asked to add 46 to 37 and round the result to the nearest ten. he figured that since he was going to have to round anyway, he might as well do it before adding the numbers. he rounded 46 to 50 and 37 to 40, thus getting an answer of 50+40=90. this answer is not correct. what is the correct answer?

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
