Angles V, U, and X are all marked with a single swish. That means that they all measure the same thing, 50 degrees. By the Triangle Angle-sum Theorem, all the angles inside a triangle add up to equal 180, so angle VWU = 180 - 50 - 50 which puts angle VWU as 80 degrees. Angle VWU is vertical to angle ZWX, and since vertical angles are congruent, then angle ZWX also equals 80 degrees. That means that angle WZX is 50 degrees. Hope that helps because I'm having a hard time trying to decipher what your answers are. They are a bit crammed together.
