Problem

Point A′ is the image of point A under a rotation about the origin, (0,0).
An XY coordinate plane. The horizontal x axis runs from negative 8 to 8 in intervals of 1. The vertical y axis runs from negative 8 to 8 in intervals of 1. A solid point labeled A is plotted at (negative 3, 4). A solid point labeled A prime is plotted at (3, negative 4).
Determine the angles of rotation.
