Using a calculator, we can find the values of sin 5, sin 61, cos 85, and cos 29:

sin 5 ≈ 0.087
sin 61 ≈ 0.874
cos 85 ≈ 0.087
cos 29 ≈ 0.874

Now we can substitute these values into the expression:

sin 5 + sin 61 - cos 85 - cos 29 ≈ 0.087 + 0.874 - 0.087 - 0.874
≈ 0.961 - 0.961
≈ 0

Therefore, sin 5 + sin 61 - cos 85 - cos 29 ≈ 0.
