Answer:
∠ZWY ≅ ∠XYW by the alternate interior ∠s theorem,
WY ≅ WY by the reflexive property
WZ ≅ XY by the given.
Step-by-step explanation:
The option:
- WX ≅ ZY by definition of a parallelogram
can't be used because we want to prove that WXYZ is a parallelogram
The Alternate Interior Angles Theorem states that, when two parallel lines (here XY and WZ) are cut by a transversal (here WY), the resulting alternate interior angles (here ∠ZWY and ∠XYW ) are congruent.
The reflexive property of congruence states that an angle, line segment, or shape is always congruent to itself. Here, WY ≅ WY.
Since the denominators are already equal to each other, all you have to do is add the numerators.

Answer:
Alternative A is the correct answer.
Step-by-step explanation:
For a function to have y-axis symmetry then it must be an even function such that; f(-x) = f(x). In alternative A, y = x^2 is an even function since; y(-x) = (-x)^2 = x^2 = y(x). The second function is also even since it has the absolute symbol. Finally, the cosine function is always an even function since cos(-x) = cos(x)
