    Answer:

    Cos A < 0 in the 3rd and 4th quadrants

    Tan A < 0 in the 2nd and 4th quadrants

    Step-by-step explanation:

    In trigonometry, we make use of the ACTS initials to get which quadrant has it’s sine, cosine or tangent functions as negative or positive.

    In quadrant 1, it is denoted by A meaning All of sine, cosine and tangent functions are positive

    In quadrant 2, it is denoted by C to mean that only cosine is positive i.e. greater than 0.

    In quadrant 3,it is denoted by T to mean that only cosine is positive i.e. greater than 0.

    In quadrant 4, it is denoted by S to mean that only sine is positive i.e. greater than 0.

    Thus, comparing all above with the question, we can say that;

    Cos A < 0 in the 3rd and 4th quadrants

    Tan A < 0 in the 2nd and 4th quadrants
