two-thirds of the cosine of 60 degrees.
So two-thirds times one-half is one-third.
Answer: 1/3

I think there is some character code issue in the post, for example i see "2?3" ie "2 question mark 3" and "? [question mark] this is sqrt right? " which makes me think that the question mark was possibly supposed to be a square root sign, and not a division sign... in which case the solution would read:
So, did you mean (2 divided by 3) * cos(60 degrees) , or 2 * sqrt(3) * cos(60 degrees) ?
