I drew the same double-slit setup twice, but on the right I showed the angle as being between the axis and the line from the midpoint of the two slits and the 1st point of deconstructive interference.
I'm confused how the equation a * sin(theta) = n * lambda still holds as x != n * lambda and y != a in this case. Am I thinking about this correctly?
