The answer is A.
(sqrt(6)+sqrt(2))/4

You can solve this using the unit circle, or simply enter cos(pi/12) into your calculator then type those possible answers into your calculator and see which answer equals the same as cos(pi/12).

Answer:

d = $\sqrt{74}$ or 8.60

Step-by-step explanation:

(5, 8) (-2, 3)

Let 5 = $x_{1}$

8 = $y_{1}$

-2 = $x_{2}$

3 = $y_{2}$

Plug in the values into the equation to get the distance:

d = $\sqrt{(x_{2}-x_{1})^{2} + (y_{2}-y_{1})^{2} }$

d = $\sqrt{(-2-5)^{2} + (3-8)^{2} }$

d = $\sqrt{(-7)^{2} + (5)^{2} }$

d = $\sqrt{49 + 25}$

d =  $\sqrt{74}$ or 8.60
