    Answer:

    To find the value of cos 180 degrees from the Cartesian plane, the value 180 degree takes place in the second quadrant. As the cosine values in the second quadrant always take a negative value. From the value of cos 0, we will obtain the value of cos 180°. It is also represented in terms of radians.
