If `alpha, beta` are real, what is `|(alpha+ibeta)/(beta+ialpha)|` equal to ?

If alphaand beta are real them |(alpha+i beta)/(beta+ialpha)|=

If alpha and beta Are different complex number with |alpha|=1, then what is |(alpha- beta)/(1-alpha beta)| equal to ?

If sin (alpha+beta)=1, sin (alpha-beta)=1/2 , then tan (alpha+ 2beta). tan (2 alpha+beta) is equal to :

If sin(alpha + beta) = 1 , sin(alpha - beta) = 1/2 , then : tan(alpha + 2beta)tan(2alpha + beta) is equal to :

If alpha and beta are the zeroes of the polynomial x^(2)+4x-77, then the quadratic polynomial whose zeroes are (alpha+2 beta)/(alpha+beta) and (2 alpha+beta)/(alpha+beta) can be equal to
