Answer:
120 degrees
Explanation:
If you look at the top left of the image, you can see angle A is 120 degrees. Then, if you look in the bottom left, you can see that angle H is 60 degrees. Since A and E are corresponding exterior angles, that means that overlap each other. So, since angle A is 120 degrees, so is angle E. Another way you can figure this out is by simply recognizing that a straight line is equal to 180 degrees. Since angles E and H form the straight line, you can simply subtract the 60 degrees, marked by angle H, from 180 degrees, the total measurement of the line, in order to get 120 degrees, which is angle E. I hope this helps!
