    Work: Calculate the value of equation arccos((25×cos20.483)/(25+2×1×cos13)) .
    Question type: Mathematical calculation
    Solution:
          arccos((25×cos20.483)/(25+2×1×cos13))
        =arccos((-1.565175)/(25+2×1×cos13))
        =arccos(-1.565175/26.814894)
        =arccos(-0.05837)
        =1.6292

    Answer:arccos((25×cos20.483)/(25+2×1×cos13))=1.6292
