Are those 2x6 rafters which are 24" on center?
Having a low pitch, heavy snow load weight could suddenly collapse the roof in the middle, or slowly 'swayback' the ridge beam which would push the center of the walls out.
The triangle structure takes a bit of that load and drops it onto interior load-bearing walls. Hopefully that wall is over an I-beam in the basement holding up the first floor. You can measure from the edges of the perimeter and follow it all the way down.
It's a bit of a (insufficient and on an angle) hack but the right idea.
Snow would make all the difference if more is needed.
