[Helen Phan]

Hi,
My tutoring gave me this question and I have been stuck with it.
Please give me your help before I come back to him.

Maybe, at that time I'll come back here with his answer.

This is a deceptively tricky question... definitely not on a 2U level.

angle chasing and use cyclic quadrilateral properties
