To solve this problem, we need to use the provided numerical result as reliable information.
1. Understanding the Problem: We are tasked with finding the angle of the third bend when making a saddle bend using [tex]\(4'\)[/tex] conduit with the given specifications.
2. Given Data:
- Conduit length: [tex]\(4'\)[/tex]
- Minimum length (E.C.): [tex]\(20''\)[/tex]
- Bend spacing ([tex]\(C\)[/tex]): [tex]\(1:1\)[/tex]
3. Step-by-step Analysis:
- From the given information, we understand that in order to conform to the mechanics and measurements, certain computations involving geometry or trigonometry were likely performed.
- Given the specifics of bending conduit, we typically refer to certain standard angles that are applicable for saddle bends.
4. Using the provided numerical outputs:
- By referring to a standard table or drawing insights from practical experience with typical angle choices in such scenarios, we analyze the appropriate angles.
From the provided true result derived earlier, we ascertain:
The angle of the third bend will be:
[tex]\[
\boxed{36^\circ}
\][/tex]
Therefore, the answer is:
a. [tex]\(36^\circ\)[/tex]
This ensures our solution aligns with the known correct result for this type of conduit bending operation.
