Answer:
x=22.5 degrees
Step-by-step explanation:
angle EAB is congruent to AED because alt int angles, so EAB is equal to 2x. There's a theorm that says that one exterior angle is equal to the measure of the other 2 angles, so that means angle AEB is equal to 4x because 2x plus 4x is 6x. If you extend the lines, you will find that 8x is equal to 180 degrees and 180/8 is 22.5 degrees.
