Question #7 and #8 Thank you

7. If the part and IR are parallel and x-ray tube is perpendicular but IR is off center, will this cause any shape distortion? Why or why not? (2 points) 8. A 20 degree caudal angle was used on a a PA projection, how would the angle change to produce the same image? (1 poin) particular AP exam. If the patient had to be imaged with
