Answer:

20

Step-by-step explanation:

Im not dumb at least i dont think so but why would she use 180? Its not a triangle and its not a straight line sooo... wouldn't it be

5x = 100

5x/5 = 100/5

x = 20

the mistake is that you put 180 and its an angle relationship so its not 180 (a straight line)
