if thats to scale than its either 105 or 130. but usually these diagrams aren't to scale haha
 
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
 
i know HKI is not the marked right angle one. i said that i forgot a right angle is actually 90 and not 50. yes i realize i'm dumb, its been awhile since geometry
 
i had a feeling B was right.. thank you all +k (even though only 2 of you weren't already at 10/10)

we'll see when i finish and submit

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.
