It's been awhile since I took geometry but that appears to be correct. How did you conclude that it was 49 degrees though?
OpenStudy (jtug6):
I'd wait for someone else to help you work through it. Perhaps @mathmale?
OpenStudy (jtug6):
Or @Astrophysics
OpenStudy (jtug6):
How would you go about first finding JSL given that angle JSR is 53 degrees? (There's probably an easier way about solving with the use of a postulate but I don't remember)
OpenStudy (jtug6):
angle JSL I should add

x + y + 78 = 180
Since m<JSR = 53, and angles JSR and LSN are vertical angles, then m<LSN = 53.
x + 53 + 78 = 180
x + 131 = 180
x = 49
m<LNS = 49

Aren't we supposed to guide them through it?

terrible...

He already got the answer. He said above it was A. That answer is correct.

i am sorry to say this but i am not a boy I am a girl
OpenStudy (anonymous):
lol
OpenStudy (mathstudent55):
Don't be sorry. Sorry to refer to you as "he".
I'll rewrite it then.
