Question

28. If mZDEF = 103, then what are mZFEG and mZHEG? The diagram is not to scale.FEA. mZFEG = 77, mZHEG = 113B. mZFEG = 103, mZHEG = 77C. mZFEG = 87, mZHEG = 103D. mZFEG = 77, mZHEG = 103

Answer 1

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
