whats your question?

anonymous · Answer

not sure how to figure this out exactly

alekos · Answer

what is it that you are after??

anonymous · Answer

i know that the cirlce is divided in half or 180* in several places. CE & BD

alekos · Answer

yeah thats all very good but what does the question want you to find out?

you have written "what is?'

anonymous · Answer

find the measure of arc BC

anonymous · Answer

sorry I guess I didn't actually include that in the question.

anonymous · Answer

So if arc BD is 180* I would subtract angle C 45* from that correct?

anonymous · Answer

but what would I do next to find the answer?
