thanks!!

Okay, so the degrees of a straight line are equal to 180, so the line GED = 180 degrees. Now, as DEI = 39 degrees and HEI is a right angle, so it equals 90 degrees, the angle GEH = 180 - (90 + 39).degrees therefore, = 180 - 129 degrees therefore, GEH = ? degrees

OpenStudy (anonymous):

ok i think it is 141 because that there is a 39 degrees on the line so i think it is 141 am i correct? I know that a line is 180 total degrees so did i get it right?? 141+39=180

OpenStudy (anonymous):

so did i get it right???

OpenStudy (lncognlto):

You're almost correct; however, you are neglecting one other angle also present on GED, namely HEI, which is a right angle and equal to 90 degrees.

OpenStudy (anonymous):

that is not an answer because i got 129

OpenStudy (anonymous):

ok so i get the right angle thing but what about the answer?? The answer is incorrect!

OpenStudy (lncognlto):

And now we subtract 129 from 180 to get the degrees of the missing angle. So 180 - 129 = ?

OpenStudy (lncognlto):

129 isn't the answer; 180 - 129 is.
