Since the wires are going to make an X, if one angle is 72 deg, then you know the angle directly opposite to it is also 72 deg. Looking at a single side of the x, you see there is a total 180 deg angle (72 + unknown angle), so the unknown angle is 180 - 72, and the angle directly opposite to it will be the same.

Your reasoning is correct. Since the wires make an X shape, if one angle is 72 degrees, then the angle directly opposite it will also be 72 degrees. Additionally, if you look at a single side of the X, you can determine that the angles on that side add up to 180 degrees. Therefore, the unknown angle can be found by subtracting 72 degrees from 180 degrees, giving you 108 degrees.
What part of the coordinate plane is equidistant from the points A(–3,2) and B(3,2)? Explain your answer in two sentences.
The part of the coordinate plane that is equidistant from points A(–3,2) and B(3,2) is the horizontal line passing through the point (0, 2), specifically the y-axis. This is because any point on that line has the same y-coordinate as A and B, making it equidistant from both points.
