    Why would you even want to build it? It has no purpose… Water wise, you need a goesinta, and a goesauta for it to have any real use.

    Is that the left side of a recliner made of copper?

    After you make that expensive repair and you still have the same problem, What will you check next?

    If those are 45 degree offsets, it's

    1. 1.41 X the offset (center to center)
    2. Deduct for the distance from end of tubing to center of fitting.
    3. The offset & advance are the same

    Example:

    If you have a 12" Offset, the travel piece will be 17"s.

    As Dan asked, is this for class, a project or License?

    That's a semi-odd illustration/math problem, took me a moment to understand the 'handwritten' numbers are given numbers. And, what bizarre angles, one pic seems to be 45s and another seems to be 22 1/2 or 11 1/4.

    Size of the pipe doesn't matter, these are center-to-center measurements, not the actual length of the pipe (in a real world scenario)

    Are we to assume 45 degrees? Then the .707 and the 1.414 kicks in.

    I give up, they don't give any clues. Are you supposed to assume G and M are 1/3's of D?

    If we assume that, how does one assume the other letters? E,F and L,K?

    Time to send this quiz writer back to school, is my answer

    Are all the connections either 90º or 45º? Are we supposed to determine which is which visually?
