Answer:
The answer is "5 or 35".
Step-by-step explanation:
It also is important to understand the difference in the AP and PA predictions, and we will talk regarding their difference, and maybe we'll take the circumstances.
It is called the PA view during the process of x-ray and as the x-ray passes from its body back to both the foreground.
Its direction was its reverse throughout the AP view. Now let's understand what critical it's really. So less the distance among object and display was also created, much clears the shadow, and according to physics concepts x-ray was its light source in this instance, but we're the target. In AP display's the rear side, which means good shadow, whereas the implications of alternative give better shadow in the PA view.
If talking around the same picture, the angle difference between both the AP and the PA visual is maximum of 15-20°.
Its situation indicates a caudal angle of 20° for the AP test. So, it must be for PA:
