Answer:
62°
Step-by-step explanation:
∠IKD=∠EIB=∠GJI =118° (Corresponding angles)
∠GJI+∠AJG=180° (Linear Pair)
∴∠AJG= 180°-118°
=62°
When shrinking an image, the size of each side is shrunk by the scale factor. However the area is not shrunk by the same factor. Area is a squared measurement (when finding the area of a rectangle we take length x width; two measurements, so a squared answer), so the area will be shrunk by the scale factor squared; in this case the area is shrunk by 3² or 9. This means the new area would be 720/9 or 80 square inches.
