Im confused in this one @Hoslos do you get it?

OpenStudy (rainbow_rocks03):

crazy right?...and I am only in the 6th grade! :0

OpenStudy (legends):

Im guessing D

OpenStudy (anonymous):

Let me see...

OpenStudy (legends):

It has to be D because there is no way that ACD is greater than CED

OpenStudy (anonymous):

The section GCD makes a right triangle and angle GCD is 90 degrees. Then if ACG is 50degrees, then ACD is 90-50=40 degrees.

OpenStudy (anonymous):

The line CEF is measures half of a revolution or 180 degrees at E. Hence, if DEF is 145 degrees, then CED is 180-145=35 degrees. Answer becomes A.
