Answer 2

To calculate the value of the expression 2 cos 60°, we first need to know the value of cos 60°.

Cosine is a trigonometric function, and for the angle 60°, its value is 1/2. Therefore, cos 60° = 1/2.

Now, we can substitute this value into the original expression:

2 cos 60° = 2 * (1/2) = 1

So, the value of the expression 2 cos 60° is 1.
