hi again
OpenStudy (anonymous):
can i get a medal
jimthompson5910 (jim_thompson5910):
what do you have so far?
OpenStudy (anonymous):
You get medals by answering questions, please only comment about the problem itself.
@jim_thompson5910 - I'm not sure how to start this one.

well i got 360
OpenStudy (anonymous):
Once again, please support your reasoning.
jimthompson5910 (jim_thompson5910):
focus on angles a and b, if you combine them you get a full circle (ie full revolution) right?
OpenStudy (anonymous):
2 KJM + 2 KLM = 360
OpenStudy (anonymous):
@jim_thompson5910 Yes.

how does angle KJM relate to arc KLM
OpenStudy (anonymous):
a = 2 x angle KJM, b = 2 x angle KLM, and a + b = 360
OpenStudy (anonymous):
Anything related to Inscribed angle Theorem?
jimthompson5910 (jim_thompson5910):
yes you are on the right path
jimthompson5910 (jim_thompson5910):
KJM is an inscribed angle

Inscrib. angle theorem: half of the central angle is 2a degrees, thus, it would be option C, correct?
jimthompson5910 (jim_thompson5910):
close
jimthompson5910 (jim_thompson5910):
angle 'a' is actually twice as big as KJM
angle 'b' is twice as big as KLM
jimthompson5910 (jim_thompson5910):
flip things around:
angle KJM = (1/2)*(angle a)
angle KLM = (1/2)*(angle b)
OpenStudy (anonymous):
isn't that what I said :(
