Find an acute angle `theta` , when `(costheta-sintheta)/(costheta+sintheta)=(1-sqrt(3))/(1+sqrt(3))`

If (costheta-sintheta)/(costheta+sintheta)=(1-sqrt(3))/(1+sqrt(3)) , then find the value of theta .

sintheta+costheta=(sqrt(3)+1)/(2)

sqrt(3)costheta+sintheta=2

Prove that (1+costheta+sintheta)/(1-costheta+sintheta)=cot(theta/2)

sqrt(3)costheta+sintheta=2 then theta =

Suppose that costheta=-1/2 and theta is in the 2nd quadrant prove that (4tantheta+4sintheta)/(3costheta-3sintheta)=(4sqrt3)/(3(1+sqrt3))

sintheta - sqrt(3)costheta =1

Write the acute angle theta satisfying sqrt(3)sintheta=costheta .

if (1-costheta)/(sintheta)=(sqrt(3))/(3) , then theta =
