Answer:
ok these are the same angles so they are equal so
4x-9=3x+29
+9
4x=3x+38
-3x
x=38
Hope This Helps!!!
Step-by-step explanation:
Since Angle DAE = Angle BCE, lines AD amd BC are parallel (by Z-angles).
This means that Angle ADE = Angle CBE (by Z-angles).
We have 2 congruent angles and 1 congruent side (AD = BC, given).
By ASA congruence, triangles AED and CEB are congruent.
