Your answer is going to be D none of these because supplementary angles are angles that two letters are across from its not A because G, and Z are correct but not H, and X its not B because neither H, and X are not supplementary angles and when it came down to rather C, or D I choose D because neither H, and X or E, and X are supplementary angles that's why I had to choose D because it was the only logical answer. Your answer is D.
