Why would you fly 12 miles from the VOR and then turn around to go back out
and intercept the 19 DME arc? V187 does not appear to be depicted on the
approach plate. What was the IAF?

Your best answer to this question would be to get a PPL, and then and IR
with a competent instructor, who could easily answer the questions.

Otherwise, why start another ridiculous discourse when you blatantly are
announcing your naivete to the world?
