I'm going assume X=A and M=S. This means that x+80=4x+8.
This shows x is 24. That also means a is 24. A parallelogram has 360 degrees in total. I have to do 360-24-24/ 2 to find the answer for M.
360-24-24/2 = 312/2=156=M
This shows that M is 156. Please note that this answer might be wrong and that this my first time answering a question on this forum. If you have any comments, questions, or concerns please let me know.
