How do I constrain all sides. When I try I get "Sketch could not be solved"

When I try to constrain this part in my sketch it shows everything in red. But i've been told everything must be constrained for best practice. I cannot figure out how to do that.

That 37 is unnecessary because the whole thing is 145 and you've got other horizontal dimensions (5, 83, 10, 10). What's missing is the height of that right rectangle.

The length dimension (37) is already implied by the other dimensions (145-5-10-10-83 = 37) so you cannot add a driving dimension without overconstraining it all and making it go red. What you do need is some sort of dimension for the vertical spacing of those 2 blue entities. Or otherwise add a constraint to make them align vertically with the 83mm long line segment. Add one such thing and the whole sketch will be fully defined,
