Question

Sin(10) × cos(20) + 0,5 × sin(10)

Answer 1

Sin(10) × cos(20) + 0,5 × sin(10)=0,25

Answer 2

To evaluate the expression, we can use the values of sin(10) and cos(20) in radians. Here's the calculation:

sin(10) ≈ 0.17364817766693033 cos(20) ≈ 0.9396926207859084

Now we can substitute these values into the expression:

0.17364817766693033 × 0.9396926207859084 + 0.5 × 0.17364817766693033

Calculating this expression gives us:

0.16258320859906992 + 0.08682408883346516

Adding these two values together:

0.16258320859906992 + 0.08682408883346516 ≈ 0.24940729743253508

Therefore, Sin(10) × cos(20) + 0.5 × sin(10) is approximately equal to 0.24940729743253508.
