simply use the Inscribed Angles Conjectures which says that the measure of the intercepted arc angle is twice that of the inscribed angle.

Thus a = 65 - Jan 12th 2008, 12:59 PMzachcumer
so number 2...well the line where the dot is is 180 degrees, so does that have anything to do it. still a little confused...

on number 2 is b= 30 degrees?

right

one quick one: so on problem 3, to get that you take 95(2) (thats 95 times 2) which would equal c+120 degrees. But why. Why times 2
