Rewrite each expression as a function of a single angle.
You do not need to solve for the function at that angle.

~~~~~~~~~~~~~~~~~~~~~ 


Use the formula of adding arguments for tangent function

    tan(a+b) = 


and get

   = tan(28°+77°) = tan(105°).    ANSWER


The last expression is what you want to get.

Solved.
