Answer 2

To calculate the product of the sines of the given angles, you can simply multiply them together:

sin(12°) × sin(24°) × sin(48°) × sin(84°)

sin(12°) ≈ 0.2079 sin(24°) ≈ 0.4226 sin(48°) ≈ 0.7431 sin(84°) ≈ 0.9877

Now, multiply these values together:

0.2079 × 0.4226 × 0.7431 × 0.9877 ≈ 0.064

So, the product of sin(12°) × sin(24°) × sin(48°) × sin(84°) is approximately 0.064.
