Respuesta :

Angles DEF and FEG both occur on a straight line and are therefore altogether equal to 180 degrees. Thus, FEG equals

180 - DEF = 180 - 103 = 77 degrees.

FEG = 77 deg

Angle HEG also occurs on a straight line with FEG and both are therefore altogether equal to 180 degrees.

HEG = 180 - 77 = 103 degrees

HEG = 103 degrees

Option D is your answer
