Detailed Solution

Given is a figure,

AB | | CD,

∠

EAB

= 50 °

∠

ECD

= 60 °

The alternate interior angles between two parallel lines are congruent.
Now, Since,

∠

ECB and

∠

EBA are alternate interior angles between

B | | CD

, therefore,

∠

ECD =

∠

EBA=

60 °

Now in triangle AEB, equate the sum of interior angle to

180 °

\Rightarrow

∠

EBA+

∠

EAB+

∠

AEB

= 180 °

\Rightarrow 60 ° + 50 ° + ∠ AEB = 180 °

\Rightarrow 110 ° + ∠ AEB = 180 °

\Rightarrow ∠ AEB = 180 ° - 110 °

\Rightarrow ∠ AEB = 70 °

Thus, the value of is

∠

AEB=

70 °

.
Therefore, option (4) is correct.
