Not sure what you're asking. There are 3 equations and 3 unknowns.
1. 8.25^2 + (4-a)^2 = c^2
2. 0.5^2 + b^2 = a^2
3. 0.5/8.25 = b/4
Solve the third equation for b (b = .2424)
Solve the second equation for "a" after plugging in "b" (a = .5557)
Solve the first equations for "c" after blogging in "a" (c = 8.94)
For the angle it's just the tangent inverse of (4-a)/8.25. You could have solved for c using the sin or cosineif you wanted, too.

I didn't follow how you got step 3.

A rhombus has equal sides.
Looks like some rafter math could be involved. A carpenter framing square sure sounds handy, if you know how to use one.

Your equation 3 is wrong. The two triangles are not similar.
