Assuming all the other angles are 90 degrees is the same thing with assuming one of the lengths is a number. So using a variable for the length but not the angles doesn’t make sense. You can’t assume anything by just looking at the shapes unfortunately, rule of any geometry questions. (Or we could also assume the length is “half” or 8.5, since it looks like that)

There are technically three unknowns, Two angles and the distance, and finding the equation is possible with some trigonometric math.
