Final answer:
Without specific information on the bending shoe's scale or radius, an exact distance between the 22.5° and 45° center marks cannot be determined. Typically, one might expect the 45° mark to be twice as far as the 22.5° mark if the scale is linear.
Step-by-step explanation:
The student's question pertains to the measurement between different degrees of bends on a bending shoe, a tool used in bending pipes or conduits. While the provided reference information seems unrelated to the question at hand, generally, the distance between marks on a bending shoe depends on the shoe's specific design and the scale used. If we were talking about a linear scale where angles were marked consistently along the bend, you could expect that the distance between a 22.5° center mark and a 45° center mark is proportional to the angles themselves. Since 45° is double 22.5°, it would be reasonable to find the 45° mark is twice as far from the starting point as the 22.5° mark. However, without specific information about the bending shoe scale or radius, we cannot determine the exact distance between these two marks. In practice, the best approach to obtain this distance would be to refer to the bending shoe's manual or use the shoe itself to measure the distance directly.
