Best ResponseYou've already chosen the best response.2Yes, GH intercepts an angle of 360/12 = 30 at the center. Angle GAH is the inscribed angle of GH, so it must be 30/2 = 15

Best ResponseYou've already chosen the best response.0okay so say if your finding an angle like KAH how would you find it

Best ResponseYou've already chosen the best response.2First find the central angle : 30+30+30 = 90 dw:1438319490988:dw

Best ResponseYou've already chosen the best response.2simply divide that central angle by 2 to get the inscribed angle KAH

Best ResponseYou've already chosen the best response.2Yep, arc FB intercepts 120 degrees at the center, so we say arc measure of FB is 120 degrees.

Best ResponseYou've already chosen the best response.0ok thank got my calculations wrong i just have one more JNH and ANE would measure up to 180 right?

Best ResponseYou've already chosen the best response.2180 degrees is a flat straight angle : dw:1438321024820:dw

Best ResponseYou've already chosen the best response.2do the angles JNH and ANE really look flat ?

Best ResponseYou've already chosen the best response.0oh well at first I took 180x.5 to get 90 but I wasnt sure and no its not 180 because they are not flat

Best ResponseYou've already chosen the best response.2they are not flat, good, lets figure out how to find that angle

Best ResponseYou've already chosen the best response.2Use trianlge exterior angle theorem in triangle AJN : \[\angle ANE = \angle AJN + \angle NAJ\] dw:1438321365859:dw

Best ResponseYou've already chosen the best response.2Can you find the angles AJN and NAJ ?
