Answer:
14°
Explanation:
Angle DCE is congruent to Angle GDF
To find the measure of Angle CDF, you need to find the measure of Angle DCE first.
360° = 76° + 90° + Angle DCE + 90°
360° = 256° + Angle DCE
Angle DCE = 104°
Then you subtract 90° from 104° (Angle DCE) to get the measure of Angle CDF
104° - 90° = 14°
Angle CDF = 14°
