135 degrees because 180-45=135 and due to the lines being parallel, the interior angles are equal.
In order for us to find the mean of the given numbers above, what we are going to do is to add up all the numbers and divide them by the number of items. So the sum of all the numbers is 120. Now divide 120 by 12 and the answer is 10. Therefore, the answer is option D. 10. Hope this helps.
Based on the indices of the regular polygons, the number of sides that X has is 8. See the computation below.
<h3>What is the analysis for the above solution?</h3>
Assuming that X has G number of sides; and
Y has H number of sides, this means that:
G-H = 3 ...........1
Recall that the formula for the exterior angles is:
360/n; where n is number of sides
X = 360/G
Y = 360/H
(360/G) + (360/H) = 117°.......2
Solving 1 and 2 simultaneously, we obtain:
G= 8 and
H = 5
Thus, X has 8 sides.

You have 4 green picks and, after adding some orange picks, you know that every 2 picks from 3 are orange.
So, 1 green pick needs 2 orange picks, three in total. Since you have 4 green picks, then you will have in total 3·4=12 picks (4 green and 12-4=8 orange).
Answer: there are 12 picks in total.
