A.
121°

B.
47°

C.
239°

D.
217°

Answer 1

Look here angle CDF + angle CDG + angle GDF = 360

This is because they all are around a point. So now you can find out the value of angle CDG :)

Answer 2

I dont get it..

Answer 3

I think my answers A.

Answer 4

Plug in the measure of each angle into the equation CDF+CDG+GDF=360

Answer 5

yes the answer is A :)

Answer 6

:) yup
