    Answer:

    Step-by-step explanation:

    cos 600° = -0.5

    sin 30° = 0.5

    sin 30° * cos 600° = -0.5*0.5

                                  =-0.25

    Answer:

    ¼

    Step-by-step explanation:

    sine and cosine are complementary

    => sinθ = cos(90°-θ)

    => sin30° = cos(90°-30°) = cos60°

    => sin30°×cos60° = sin²30° = ½² = ¼
