Answer 2

To simplify this expression, you can use the trigonometric identity:

sin(A + B) = sin A cos B + cos A sin B

Using this identity, you can write:

sin 74 = sin (37 + 37) = sin 37 cos 37 + cos 37 sin 37 = 2 sin 37 cos 37

Substituting this expression into the original equation, we have:

12 sin 74 / (sin 37 sin 53) = 12 (2 sin 37 cos 37) / (sin 37 sin 53) = 24 cos 37 / sin 53 ≈ 18.145

Therefore, the simplified value of the expression is approximately 18.145.
