First, let's break down the trigonometric functions:
sin 130° ≈ 0.766 (rounded to 3 decimal places) cos 50° ≈ 0.643 (rounded to 3 decimal places) tan 80° ≈ -0.176 (rounded to 3 decimal places) cos 150° ≈ -0.866 (rounded to 3 decimal places)
Now, multiply these values together:
0.766 0.643 (-0.176) * (-0.866) ≈ 0.092
Therefore, sin 130° × cos 50° × tan 80° × cos 150° ≈ 0.092.
