If a vector $\vec { A }$ has components A_x 0,and A_y

Question

If a vector $\vec { A }$ has components A_x > 0,and A_y < 0,then the angle that this vector makes with the positive x-axis must be in the range A)0° to 90° B)90° to 180° C)180° to 270° D)270° to 360° E)cannot be determined without additional information

Quizplus · Accepted Answer

Given that the x-component of the vector $\vec{A}$ is positive ($> 0$) and the y-component is negative ($< 0$), the vector lies in the fourth quadrant. In the Cartesian coordinate system, angles in the fourth quadrant range from 270° to 360°.
