Answer:
you have it correct, permutation
Step-by-step explanation:
As per the problem,
Marco wants to use the distributive property to find the value of 17 • 69 + 17 • 31.
We have been asked to find , which expression can be used?
As per the distributive property , we know that

Now apply this on the given expression we get

Hence the expression , which can be used is 17(69+31)
First we need to see in which quadrant 11pi/6 lies And it lies in fourth quadrant. And to find the reference angle in the fourth quadrant, we need to subtract the given angle from 2 pi . For e.g if the angle is 5pi/3, then the reference angle is 2pi - (5pi/3) = pi/3 .
So for the given question, reference angle of 11pi/6 is

And that's the required reference angle .
The Correct Answer Is...
<em><u>For the most part, very impractical.</u></em>
