The distance between the double slit and the screen is $$a$$. The distance $$x$$ is measured from the main maximum to some bright or dark interference fringe. The hypotenuse is $$h$$. And $$\theta$$ indicates at which angle the considered interference fringe is located. From this you can get the relation:$\sin(\theta) ~=~ \frac{x}{a}$
