[1/1 Formula]
    Work: Calculate the value of equation 0.5*25*sin50*sin18/(sin112) .
    Question type: Mathematical calculation
    Solution:
          0.5*25*sin50*sin18/(sin112)
        =0.5*25*sin50*sin18/(-0.889996)
        =0.5*25*-0.262375*sin18/-0.889996
        =0.5*25*-0.262375*-0.750987/-0.889996
        =12.5*(-0.262375)*(-0.750987)/(-0.889996)
        =(-3.279688)*(-0.750987)/(-0.889996)
        =2.463003/(-0.889996)
        =(-2.767432)

    Answer:0.5*25*sin50*sin18/(sin112)=-2.767432
