Express -2 in triganomic form

now, there are two possible angles for that tangent... however, let's look at our a,b components.

"a" is negative whilst "b" is positive, so is not 0 then, thus

The answer would be c

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
