In this problem you can reflect the small triangle and you will see that the angle D is equal to the angle x, and the angle E is equal to the angle B so we can sum tyhe internal angles of the big triangle to find x so:

[tex]x+81+30=180[/tex]

And we solve for x so:

[tex]\begin{gathered} x=180-81-30 \\ x=69 \end{gathered}[/tex]

the angles x is equal to 69º
