Answer: B.
Explanation:
Consider any right triangle that has both its legs of same length. In this case both the other two angles would be 45 degrees each. Now, if both its legs are considered of unit length, then hypotenuse would be of length √2.
The cos 45 = 1/√ 2 = √ 2/2
Hope this helped! :)
If I understand your question correctly, e and 6 would be e + 6 and one half it would be:
(e + 6) / 2
I think it is they both pay the same
