CSWP segment 1?

I've been trying this cswp question for a long time. I used all dimensions carefully but not getting any of the given answers. Question and Part is posted below. Someone can tell me where I am doing wrong? I get the correct answer for part 1 but when I change the dimensions and add new geometry to part 1, I don't get the right answer. I also post a picture of something that I believe is not correct, but I don't understand how to correct that. Thanks in advance.
Accepted answer

So, I have gone through your part. And found basically two faults:
(Refer to attached images for the respective points)
1. Angle of 130 degree was not defined. (Refer to attached image)
2. In-fact, that sketch was not defined, another dimension was missing, that might have contributed in defining the sketch.
3. Try to cross-check things out-of-the-box whenever possible, before submitting your answers.
I understand that such exams are time-bound, thus create a sense of pressure. So, try to keep calm and focus on small details like these. You'll definitely do better the next time.
All the best!
