Hello! Could someone help me answer this I got the first part right but the 2nd part wrong, even though I am pretty sure I did the math right.

a) x = 77 degrees
b) B - alternate angle
(The angle that shows 'Z' shape is alternate as both the angles are equal)

PART - 1 :
❃ Firstly , Let's explore about Alternate angles :
Alternate angles can be defined as the pair of interior angles which lies to the opposite side of transversal. It usually forms ' Z ' shape & Alternate angles are always equal.
A. [tex] \large {\tt{⟿ \: x = \boxed{77 \degree}}}[/tex] [ Since AD [tex] \parallel[/tex] EH and being alternate angles ]
The value of x is 77° .
