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

i can't solve unless i know what the line is

step-by-step explanation:

welcome to/p>

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b

i will u if u answer my question in math
