[1/1 Formula]
    Work: Calculate the value of equation 90-arctan(0.047*55)-arctan(0.03*55) .
    Question type: Mathematical calculation
    Solution:
          90-arctan(0.047*55)-arctan(0.03*55)
        =90-arctan2.585-arctan(0.03*55)
        =90-arctan2.585-arctan1.65
        =90-1.20168-arctan1.65
        =90-1.20168-1.025932
        =88.79832-1.025932
        =87.772388

    Answer:90-arctan(0.047*55)-arctan(0.03*55)=87.772388
