If sin3θ=cos(20° - θ) then find out  the value of θ.

If x cos²30⁰. sin60⁰=$${tan^2{45}^0.sec60^0}\over cosec\ 60^0$$ then the value of x : 

If A and B are acute angles and Sec A =3; Cot B=4, then the value of $$ {Cosec^{2}A}+Sin^{2}B\over {Cot^{2}A+Sec^{2}B}$$ is:

In ΔABC θ is an acute angle and tanθ is equal to three times of cotθ. Find the value of $$ {sin^{2}θ+cosec^{2}θ-{1\over 2}cot^{2}θ}$$.
