Answer:23 degrees
Explanation:
Ok! I'm a high school student so this is what I can see.
Angles A and the 130 are supper- angles meaning they add up to 180.
So that means A is 50.
Next I noticed by experience that A and B are vertical angles. So that means B is 50 as well.
And since this all have to equal to 360 angles. The equation is
360= 50+130+50+107+x or X= 360- (50+130+50+107)
And that is x=23
