42°

Step-by-step explanation:

$\angle BAE =180\degree -132\degree$

(Angles in linear pair)

$\angle BAE =48\degree$

$\angle AEB =90\degree..(\because \overrightarrow{EC}\perp\overrightarrow{ED})$

$\angle ABE = 180\degree-(48\degree+90\degree)$

(Angle sum postulate of a triangle)

$\implies\angle ABE = 180\degree-138\degree$

$\implies\angle ABE = 42\degree$

$\angle CDE =\angle ABE = 42\degree$

(corresponding angles)

$\implies x\degree=\angle CDE$

(vertical angles)

$\implies x\degree=42\degree$

$\implies x=42$

True [87]

$\huge\text{Hey there!}$

$\mathsf{(-6)2 + (-8\div 4)}\\\mathsf{\rightarrow -6(2) + (-8\div4)}\\\large\mathsf{\rightarrow-12 + (-8\div4)}\\\mathsf{\rightarrow -12 + (-2)}}\\\mathsf{\rightarrow -12 - 2}\\\mathsf{\rightarrow -14}\\\\\\\large\textsf{Therefore, your answer is: \boxed{\mathsf{-14}}}\huge\checkmark$
