If sin(y°) = cos(x°), which of the following statements is true?
triangles bac and efd in which angles b and e are right angles, the measure of angle f is w degrees, the measure of angle d is y degrees, the measure of angle a is x degrees, and the measure of angle c is z degrees
y = x and δabc ≅ δfed
w = x and δabc ≅ δfed
y = x and δabc ~ δfed
w = x and δabc ~ δfed
