Answer:

First diagonal: 7.874

Second diagonal: 8.3666

Step-by-step explanation:

We use the Pythagorean Theorem to find these.

First diagonal = 5²+6²=c²

25+36=c²

61=c²

√61=c

c=7.874

Then we use that to find the second diagonal.

7.874²+3²=c²

61+9=c²

70=c²

√70=c

c=8.3666

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)

$\implies x\degree=42\degree$

$\implies x=42$
