Answer:
x = -7
Step-by-step explanation:
2x+6 = x-1
add -6 to both sides
2x = x-7
add -x to both sides
x = -7

The Angle of rotation of the given regular pentagon after undergoing rotational transformation is; 72°
<h3>How to find the angle of rotation?</h3>
We are told that the image is a perfect pentagon that all its' sides are all equal with no uneven sides.
Now, A figure is said to have rotational symmetry if it looks exactly the same after rotating it some angle less than 360° which is a full rotation.
Now, a regular pentagon will have a rotational symmetry of order 5 because it will look the same after 5 turns.
Thus;
Angle of rotation = 360/5
Angle of rotation = 72°
