you're right i looked at this and thought it was common sense and i forgot that a right angle is actually 90 degrees not 50. i feel really dumb now

well arc GJ is 130

Well 19 is definitely b and 20 is most likely c. Its been a little while since I did this, but I think I remember this. 21 and 22 I'm having trouble figuring out what the question is asking, if you could rephrase it in terms of angles in words then that would probably help someone else.
