HELP! 25 points! I'm really bad at math and need to find out the angle of x

angle CEB and AED are corresponding angles, so they are both are equal
since we already know that CEB is equal to 160, that means that AED is also equal to 160
all you have to do to find the value of x is subtract the 115 from 160, and so you get 45
so, x=45
hope this helps!! :)
