Question

Quizplus · Accepted Answer

The direction of a vector in standard position can be found using the formula θ = atan2(y, x), where (x, y) are the coordinates of the end point. For (-3, 7), θ = atan2(7, -3) ≈ 113.2°. This angle is measured counterclockwise from the positive x-axis, indicating the vector points in the second quadrant.
