Answer:
Step-by-step explanation:
The angles diagonally opposite each other are congruent while those adjacent to each other add up to 180 degrees. You can get eight congruent angles with a transversal if the two lines are parallel, because each angle would be 90.
First subtract 8.5 from both sides, then divide the -1.2 to get x by itself
x=1.5
