If `sin32^(@)=k` and `cos x=1-2k^(2)` `alpha, beta` are the values of `x` between `0^(@)` and `360^(@)` with `alpha < beta` then

If cos20^(@)=k and cos x=2k^(2)-1, then the possible values of x between 0^(0) and 360^(@) are

If K = cos 20^(@) and cos x = 2K^(2) - 1 , then the possible value of x between 0^(@) and 360^(@) are

If sin alpha sin beta-cos alpha cos beta+1=0, then the value of 1+cot alpha tan beta is

If cos x -sin alpha cot beta sin x=cos alpha then the value of tan x/2 is

If alpha, beta are the zeros of kx^(2)-2x+3k such that alpha+beta = alpha beta then k = ?

If alpha,beta are the roots of x^(2)-k(x+1)-c=0 then (1+alpha)(1+beta)=

If cos^(4)alpha+k and sin^(4)alpha+k are the roots of x^(2)+lambda(2x+1)=0 and sin^(2)alpha+1 and cos^(2)alpha+1 are the roots of x^(2)+8x+4=0, then the sum of the possible values of lambda is

The roots of The roots of both the equation sin^(2)x+p sin x+q=0 and cos^(2)x+r cos x+s=0 are alpha and beta, Then the value of sin(alpha+beta)=
