Reproduce complicated parts

lujain_al_marhabi

Hello, 
I am trying to reproduce those two circular parts shown below, by using only two sketch features "3 point arc" and "straight" line. However, it gets pretty messy dealing with the constraints and I am not sure if I am doing it right.

and what I got so far:

can someone show me how am I doing this wrong? Thanks

I would do it like this:

On the sketch I used only circles, trims and fillets.
The first you may draw sketch with the sharp corners. Ffter that apply fillets. It will be much easiew way.
