Observe the angle in the image. The angle is measured from the positive x-axis in a counterclockwise direction.
Notice that the angle extends into the third quadrant of the coordinate plane. Angles in the third quadrant are between 180° and 270°.
Estimate the angle's position relative to the axes. The angle appears to be closer to the negative y-axis than to the negative x-axis.
Since the angle is closer to the negative y-axis, it is likely closer to 270° than to 180°.
Among the given options, 240° is the most reasonable estimate for the angle shown, as it is between 180° and 270° and closer to the negative y-axis.
