 {Answer :-}

Here, we join B and D to form BD.
Thus, AB II CD where BD is a transversal.
So, angle BDC + angle ABD = 180....(1)

Now, angle AEC = 130......... (2)

Again, 6x + angle BAE = 180.
Or, angle BAE = 180 - 6x........... (3)

Similarly, angle DCE = 180 - 4x..... (4)

We know that the sum of all the angles of a pentagon is 540.

So, angle BDC + angle ABD + angle BAE + angle DCE + angle AEC = 540.

Now, putting the values from (1),(2),(3) and (4), we have
180 + 130 + 180 - 6x + 180 - 4x = 540.
Or, 540 + 10x = 540 + 130.
Or, 10x = 130.
Or, x = 13.

Hence, the value of x is 13.

Now, second one.
Here, angle A = angle F.
angle B = angle E.
And, angle C = angle D.

Thus, after matching the corresponding angles, it will be triangle ABC similar to triangle FED.
