(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I have to find "sinθ" and "d" in the diffraction equation.

2. Relevant equations

The formula is n(lambda) = d(sinθ)

I have the n, length, width, and hypotenuse.

n=1, L=335 W=42.5 hyp=337.8

3. The attempt at a solution

I forgot how to get the angle for sin. So i'm pretty much stuck.
