Answer:

40 degrees

Step-by-step explanation:

X would be the same measurement as you can see in the diagram. you know that this is a straight angle, so you know it is 180 degrees total. subtract 100 and divide by 2 after that.

They both would be equal to the same thing. You have a 180* degree total. One angle is 100*. Which leads me to believe, both X are equivalent to 40*
