Answer 2

To simplify the expression, let's first calculate the value of the numerator and the denominator separately and then divide them.

Numerator: 8 * sin(94) Denominator: sin(47) * sin(43)

Calculating the numerator: Numerator = 8 * sin(94) ≈ 8 * 0.999847 ≈ 7.999

Calculating the denominator: Denominator = sin(47) * sin(43) ≈ 0.731354 * 0.682553 ≈ 0.499385

Now, we can divide the numerator by the denominator: Result = Numerator / Denominator ≈ 7.999 / 0.499385 ≈ 16.014

Therefore, the simplified value of the fraction is approximately 16.014.
