Step-by-step explanation:
Answer: D) 154 degrees clockwise about point A
========================================================
Explanation:
We have n = 7 sides here, so this is a heptagon.
Assuming this is a regular heptagon, then we can say that 360/n = 360/7 = 51.4285714285714 is the angle in which we can rotate the figure to have it map onto itself.
What does that mean? It means that if we were to apply this rotation, then the "before" and "after" (aka preimage and image) will be identical.
The angle value 51.4285714285714 rounds to 51, and unfortunately none of the answer choices come closer to this.
But we can scale things up. Instead of doing 1 rotation, we can do 3 rotations of 51.4285714285714 degrees each to get 3*51.4285714285714 = 154.285714285714
The value then rounds to 154 degrees. This can happen clockwise or counterclockwise.

hope it will help u in understanding
The answer would be D. an interval isnt a certain number but it is a time something happens over and over again
In order to find the range of a data set, you need to order the numbers in the set from least to greatest. Ex: 9, 3, 8, 7, 4, 1, 2, 6, 5 = 1, 2, 3, 4, 5, 6, 7, 8, 9 Then you subtract the smallest number in the data set from the largest number. Ex: 9 - 1 = 8. The answer that you get from subtracting is the range of the data set. Hope this helps.
