A vector in standard position has its terminal point at (–10, –4). What is the approximate direction angle of the vector?

The point (−10, −4) is in Quadrant III, so the direction angle must be between 180° and 270°. The reference angle is arctan(4/10) ≈ 22°, so the direction angle is 180° + 22° ≈ 202°. Therefore, the approximate direction angle is 202° (choice D).
