how kan i hewlp?
OpenStudy (anonymous):
point c is the center of the circle. if angle acb = \[1/2X+6\] and arc AB measures x+1 find x

angle acb = ?
OpenStudy (anonymous):
1/2x+6
ganeshie8 (ganeshie8):
im not sure if you mean 1/2x + 6 or 1/2(x+6)
OpenStudy (anonymous):
(1/2x)+6
ganeshie8 (ganeshie8):
okay :) simply use below property :
central angle = arc measure

OpenStudy (mayankdevnani):
but what about radius ?
OpenStudy (anonymous):
so (1/2x)+6=x+1 ?
ganeshie8 (ganeshie8):
yes solve x
OpenStudy (anonymous):
so x=10?
ganeshie8 (ganeshie8):
we're not working arc length, so radius is not needed here

ganeshie8 (ganeshie8):
yes x=10 is right!
OpenStudy (mayankdevnani):
but \[\large \bf \theta=\frac{l}{r}\]
OpenStudy (mayankdevnani):
why did you take unit radius @ganeshie8 ?
ganeshie8 (ganeshie8):
`arc length` and `arc measure` are two different things
OpenStudy (mayankdevnani):
oh !!... thank you !!

`arc measure` is same as cenrral angle
where as `arc length` is the distance along circle..
OpenStudy (mayankdevnani):
oh !! thank you very much !
ganeshie8 (ganeshie8):
agree, they are confusing terms haha
OpenStudy (mayankdevnani):
yep !
OpenStudy (mayankdevnani):
anyway, thanks for your help !
