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)

$\implies x\degree=42\degree$

$\implies x=42$

Answer:

The answer to your question is below

Step-by-step explanation:

9)

They are supplementary angle. The sum of supplementary angles is 180°.

b + 50 = 180

-Solve for b

b = 180 - 50

b = 130°

10)

They are vertical angles. Vertical angles measure the same

b = 43°

11)

They are vertical angles. Vertical angles measure the same.

b = 73°

12)

They are supplementary angles. The sum of supplementary angles is 180°

b + 35 = 180

-Solve for b

b = 180 - 35

b = 145°
