Hello!

The answer is:

The missing angle "x" is equal to 130°.

Why?

We need to remember that the sum of all of the angles of any polygon will be all equal to 360°.

So, we are given the following exterior angles:


140\°\\34\°\\56\°\\

Now, if the sum of all the exterior angles is equal to 360°, we can use it to calculate "x", so:


360\°=140\°+34\°+56\°+x\\\\x=360\°-(140\°+34\°+56\°)=360\°-230\°\\\\x=130\°

Hence, the missing angle "x" is equal to 130°.

Have a nice day!
