[1/1 Formula]
    Work: Calculate the value of equation sin(55)*(sqrt(3)-1+(sqrt(3)+1)*tan(20)) .
    Question type: Mathematical calculation
    Solution:
          sin(55)*(sqrt(3)-1+(sqrt(3)+1)*tan(20))
        =sin55*(sqrt(3)-1+(sqrt(3)+1)*tan(20))
        =sin55*(sqrt3-1+(sqrt(3)+1)*tan(20))
        =sin55*(sqrt3-1+(sqrt3+1)*tan(20))
        =sin55*(sqrt3-1+2.732051*tan(20))
        =sin55*(sqrt3-1+2.732051*tan20)
        =sin55*6.844089
        =-0.999755*6.844089
        =-6.842412

    Answer:sin(55)*(sqrt(3)-1+(sqrt(3)+1)*tan(20))=-6.842412
