a.
Sketch the given angle in standard position.
a.
Explanation of Solution
Given:
The given angle is
Calculation:
An angle is determined by rotating a ray (half-line) about its endpoint. The starting position of the ray is the initial side of the angle, and the position after rotation is the terminal side. In standard position, counterclockwise rotation of ray represents the positive angle and clockwise represents negative angle.
Hence the standard representation of the given angle is given below.
