    cos (θ) = ³/₅

    cos⁻¹[cos (θ) ] = cos⁻¹ (³/₅)

    θ ≈ 53.13

    sin (θ) > 0

    sin (53.13) > 0

    0.8 > 0

    1. tan (θ)

    tan (53.13)

    1¹/₃

    The answer is A.

    2. sec (θ)

    sec (53.13)

    1²/₃

    The answer is A.

    3. cot (θ)

    cot (53.13)

    ³/₄

    The answer is B.

    4. csc (θ)

    csc (53.13)

    1¹/₄

    The answer is C.
