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

y = w and ΔABC ~ ΔCDE

y = x and ΔABC ~ ΔCDE

y = w and ΔABC ≅ ΔCDE

y = x and ΔABC ≅ ΔCDE
