Question

If you know how, please explain. My brain is splitting in half trying to process this trigonometry stuff

Answer 1

`\huge\boxed{\text{E. } (1)/(2) }`

Explanation:

When finding the cosine of an angle, we need to note what each terms mean.

Using the acronym SOH CAH TOA, we know that the

Cosine of an angle will be it's

Adjacent side divided by the

Hypotenuse.

The side adjacent to the 60° angle is 1, and the hypotenuse of the triangle is 2. Therefore, the adjacent over the hypotenuse is
`(1)/(2)`, making the cos of 60°

`(1)/(2)`.

Hope this helped!
