I kind of understand this. I just think my math is wrong.

anonymous · Answer

missing information

anonymous · Answer

The measure of arc bc is 105. Im looking for the length of arc cd.

anonymous · Answer

This is what Im thinking. 148, the measure of angle BAD, is half 296. 296 is going to be the measure of the whole arc BD. So to find the measure of arc CD I'm thinking I do 360-105??

anonymous · Answer

Arc(BC) + Arc(CD) = 148

Find Arc(CD) from here..

anonymous · Answer

So I don't take half of it? Or do you only do that when the angle is inscribed?

anonymous · Answer

No..

Then angle is not inscribed..

It is Center Angle..

anonymous · Answer

Center Angle = Intercepted Arc...

anonymous · Answer

So:

148 = Arc(BD)

anonymous · Answer

Okay. So I do 148-105 and that gives me the answer then?

anonymous · Answer

Yes..
