Best ResponseYou've already chosen the best response.0If I add 35 + 50 = 85/2 = 42.5???

Best ResponseYou've already chosen the best response.0But yes BC passes through E and so does AD

Best ResponseYou've already chosen the best response.0when I use the formula when two cords of a circle intersect, the measure of each angle formed is onehalf the sum of the measures of its intercepted arc and the arc intercepted by its vertical angle.

Best ResponseYou've already chosen the best response.1Note that we can find angle AEB. Then you can find angle ABC.

Best ResponseYou've already chosen the best response.1Good! so now what is the angle of ABC?

Best ResponseYou've already chosen the best response.0its too small to be 50

Best ResponseYou've already chosen the best response.1Sorry... AEB = 180  angle 1 = 180 50 = 130.

anonymous

Best ResponseYou've already chosen the best response.0ok so Angle AEB is 130 and we know angle A is 35 add those and subtract 180 gets me 15 degrees?

anonymous

Best ResponseYou've already chosen the best response.0So if angle ABC is 15 degrees then the arc AC is 15

Best ResponseYou've already chosen the best response.1Are we looking for the length of the arc AC or the angle measure of the arc AC ?

anonymous

Best ResponseYou've already chosen the best response.0the measure of arc AC and the measure of angle ABC

Best ResponseYou've already chosen the best response.1Ok, the 15 is the inscribed angle of AC, so the central angle is twice of that, which is 30.

Best ResponseYou've already chosen the best response.0ok... this is because the angle of ABC is inside a triangle right...
