tan(x+100^(@))=tan(x+50^(@))tan x tan(x-50^(@))

The smallest positive value of x (in degress) for whiich tan (x + 100^(@)) = tan (x + 50^(@)) .tan xtan (x-50^(@)) is

The smallest positive value of x (in degrees) for which tan(x+100^@)=tan(x+50^@).tanx.tan(x-50^@) is

The smallest positive value of x (in degrees) for which tan(x+100^@)=tan(x+50^@).tanx.tan(x-50^@) is

The smallest positive value of x (in degrees) for which tan(x+100^@)=tan(x+50^@).tanx.tan(x-50^@) is

If tan(x + 40)^(@)tan(x+20)^(@)tan(3x)^(@)tan(70 - x)^(@)tan(50-x)^(@)= 1 , then the value of x is equal to

2tan10^(@)+tan50^(@)=2x,tan20^(@)+tan50^(@)=2y,2tan50^(@)+tan70^(@)=2w and tan20^(@)+tan70^(@)=2z which of the following is/true

Prove that: tan10^(@)tan50^(@)+tan50^(@)tan70^(@)+tan70^(@)tan170^(@)=3

Prove that, tan25^(@).tan15^(@)+tan15^(@)tan50^(@)+tan25^(@)tan50^(@)=1 .
