#### Answer

The given angle is positive; therefore, we will move counterclockwise from the x-axis as depicted in the figure:

#### Work Step by Step

Given: $2$ rad $=114.6^{\circ}$ The standard position of an angle occurs when we place its vertex at the origin of a coordinate system and its initial side on the positive x-axis. A positive angle is obtained by rotating the initial side counterclockwise until it coincides with the terminal side. Likewise, negative angles are obtained by clockwise rotation. The given angle is positive, so we will move counterclockwise from the x-axis as depicted in the figure:
