Two slits with a separation of $8$E$-5$m creates an interference pattern on a screen $2\mathrm{.}5$m away. The third$$bright fringe is a linear distance of $5\mathrm{.}39$ cm above the central bright fringe.

What is the angle, $,$ formed between this band of contructive inference and the central fringe? Answer in degrees.
