If the cotangent and tangent are reciprocals of each other, then what is the cotangent of an angle if the tangent of the same angle is b/a where a and b are not zero?

A. a/a
B. b/b
C. a/b
D. b/a

I think the answer is a/a

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
