If sin(y°) = cos(x°), which of the following statements is true?
Triangles ABC and CDE in which angles B and D are right angles, point E is between points A and C, the measure of angle A is y degrees, the measure of angle E is x degrees, the measure of angle DCE is w degrees, and the measure of angle ECB is z degrees.
a) y = w and ∠ABC ≈ ∠CDE
b) y = x and ∠ABC ≈ ∠CDE
c) y = w and ∠ABC ≠ ∠CDE
d) y = x and ∠ABC ≠ ∠CDE
