If cos(w°) = sin(z°), which of the following statements is true? triangle ABD and ECD in which angle D measures 90 degrees, angle A equals w degrees, angle B equals x degrees, angle E equals y degrees, and angle C equals z degrees z = x and ΔABD ≅ ΔECD
w = z and ΔABD ≅ ΔECD
z = x and ΔABD ~ ΔECD
w = z and ΔABD ~ ΔECD
