30 POINTS + BRAINLIEST FOR THE CORRECT ANSWER!

Question:

In the figure shown, line AB is parallel to line CD.

Part A: What is the measure of angle x? Show your work. (5 points)

Part B: Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal. (5 points)

My work:

x = 155 - 62 which leaves you with x being 53 (Credits to those who helped me in my previous asked question)
That's all I could come up with which completes part A, if you know the answer to part B feel free to just answer part B! Part A is not needed but I added it there for those who need to see it.
