Determine the smallest positive value of "x" in degree for the equation-- tan(x+100'')=tan(x+50'')* tan(x)*tan(x-50''). where "''" implies in degree. Please give a shortcut technique to solve this problem.

Dear Anurag,

Solving RHS using property: 
TanA * TanB.

and then comparing it by LHS we get the value of x.
