Solve for missing angle or solve for x

First one is 50 because the acute angles are exactly the same.

The second one is x=8 because it is the same as the other angle as well.

Here's my proof: When trying to find the first answer you can Identify that both angles are acute, and the angle is just the same as the other 50 angle.

The second one is that the angles are the same again but we have to find he equation x for it.

Hope this helps!
