Question

What is cos 60 degrees?

Answer 1

Answer:

Step-by-step explanation:

cos means adjacent/hypotenuse so for 60 degree it is 1/2

answer is D

Answer 2

For this case, we must indicate the value of Cosine (60) according to the triangle shown.

By definition we have to:

$cosine (x) = \frac {leg \ adjacent \ to \ angle \ x} {Hypotenuse}$

So, we have:

$cosine (60) = \frac {leg\ adjacent \ to \ angle \ 60} {Hypotenuse}\\cosine (60) = \frac {1} {2}$

So, the cosine of 60 is$\frac {1} {2}$

Answer:

$\frac {1} {2}$

Option D
