    Answer:

    114.89 degrees

    245.11 degrees

    Step-by-step explanation:

    cos is negative in the second and third quadrant (“pointing” on the x-axis to the left).

    so, the first answer for the second quadrant is

    114.89 degrees.

    the answer for the third quadrant is then backwards the same angles from a full 360 degree rotation

    360 – 114.89 = 245.11 degrees
