Final answer:
The total angle of rotation after a double reflection over intersecting lines is 86 degrees.
Step-by-step explanation:
When a figure is reflected twice over intersecting lines, it forms an angle of 43 degrees between the original figure and its final position. To find the total angle of rotation, we need to calculate the angle between the original and final positions of the figure after each reflection. Since each reflection over the intersecting lines forms an angle of 43 degrees, the total angle of rotation after the double reflection is 2 times 43 degrees, which is 86 degrees.
