Answer 2

To calculate the value of the given expression, we'll use a calculator or a programming language that supports trigonometric functions. Let's proceed with the calculation:

sin(10) ≈ 0.1745 sin(50) ≈ 0.7660 cos(20) ≈ 0.9397

Now, we can substitute these values into the expression:

sin(10) + sin(50) - cos(20) ≈ 0.1745 + 0.7660 - 0.9397 ≈ 0.0008

So, the approximate value of the expression sin(10) + sin(50) - cos(20) is 0.0008.
