    Work: Calculate the value of equation 2×tan(20)×(-0.64)÷45+0.0149 .
    Question type: Mathematical calculation
    Solution:
          2×tan(20)×(-0.64)÷45+0.0149
        =2×tan20×(-0.64)÷45+0.0149
        =2×tan20×(-0.64)÷45+0.0149
        =2×2.237161×-0.64÷45+0.0149
        =4.474322×(-0.64)÷45+0.0149
        =(-2.863566)÷45+0.0149
        =(-0.063635)+0.0149
        =-0.048735

    Answer:2×tan(20)×(-0.64)÷45+0.0149=-0.048735
