Answer: x=30°

Explanation:

A parallelogram always add up to 360°.

Opposite angles like F and H are always the same, so H=150°.

150+150=300 (what angles F and H add up to)

So we can do:

360-300=60

Now we know that the angle x and E have to add up to 60 but still be the same, so x will equal 30°.

We can check this by adding up all of the sides:

150+150+30+30=360°

Hope this helped :)
