Answer:

Step-by-step explanation:

cos A = 1/2      then    A = 60  tan A = tan60 = √3

sin B  =1/√2     then      B = 45      tanB =tan45 =1

now      [tanA -tan B ]/[1- tanAtanB ] = [√3-1]/[1 +√3]

                                                         =[√3-1]/[1 +√3] x[√3-1]/[√3-1]

                                                          =[√3-1]^2/[3-1]

                                                          =[3+1 -2√3]/2

                                                          =[4-2√3]/2 =2-√3

note

    [tanA -tan B ]/[1- tanAtanB ]= tan[A-B]

                                                  =tan [60-45]

                                                    =tan 15 = 2-√3
