I'll chime in as well.
Example 3 is closer to being correct, as the sprinklers at B and C
aren't more than 7'-6" from a wall, measured perpendicular to the wall.
The error, to me, is the distance of 21'-2½" between B and C. I don't
see how that would be allowable, even if you were using extended
coverage sprinklers. Table 8.8.2.1.2 limits the distance between such
sprinklers, with the maximum being 20'-0" in OH and LH occupancies.
I don't see how that would be allowed.

#2 & #3 are both wrong.
#2 is spaced too far, measured perpendicularly, from the angled wall.
#3 will require an additional sprinkler between B and C. If you
draw a 15X15 square template on your drawings you will see an
obvious void of sprinkler coverage requiring protection.

The problem with A.8.6.3.2.3 is that it only shows the one
sprinkler. What I'm concerned about is the distance between
sprinklers B and C. In example 3 all the sprinklers are spaced
correctly from the walls but B and C are 21'-2 1/2" apart. The
way I understand it, they still need to be 15'-0" along that
wall, even though they're spaced correctly from every wall. Is
that correct?

Check out A.8.6.3.2.3 it should shed some light on it.

*Subject:* Angled Wall Spacing
I am wondering if I've been thinking about sprinkler
spacing along angled walls properly. What I mean is walls
not at a right angle. The PDF I made in the link below
really helps explain it. In example 1, four heads are
spaced correctly at 225 sq. ft. In examples 2 and 3 one of
the walls is angled. My question is, are either example 2
or 3 correct, or are they both wrong? My thought is that
example 2 is incorrect, and for example 3 to be correct
there would need to be an additional sprinkler along the
angled wall between sprinklers B and C.
