Assertion (A) tan20^(@)+tan40^(@)+sqrt(3)tan20^(@)tan40^(@)=sqrt(3)Rason(R):If tan(A+B)=k, then tan A+tan B+k tan A tan B=0

tan^(2)x-sqrt(3)tan x=0

If cot 20^@=p then (tan16 0^(@)-tan11 0^(@))/(1+tan16 0^(@)tan11 0^(@))=

(tan8 0^(@)-tan1 0^(@))/tan70^(@)

The general solution of the equation tan(x+20^@)tan(x-4 0^(@))=tan(x-2 0^(@))tan(x+4 0^(@)) is

tan9^(0)-tan27^(0)-tan63^(@)+tan81^(@)

S o l v e(sin1 0^(@))^(tanx+tan3x)=tan1 5^(@)+tan3 0^(@)+tan1 5^(@)tan3 0^(@), x in (0,pi]

If tan1^(@)tan2^(@)tan3^(@)tan4^(@). . .tan89^(@)=x^(2)-8 , then find the value of x.

If tan1^(@)tan2^(@)tan3^(@)tan4^(@). . .tan89^(@)=x^(2)-8 , then find the value of x.
