Answer:

the sum of all sides = 360

therefore,100+100=200

so 360-200=160

X would be 100

this is because it is across from the other one, meaning they are the same. We also know a line is 180 and 180-100=80 so that is the angle toward the left of X. Then you would just do the same thing a line=180 180-80=100 X=100
