Work: Calculate the value of equation 228.52×(tan(45-13.091/2)*tan(45-13.091/2))-2×14.466×tan(45-13.091/2) .
Question type: Mathematical calculation
Solution:
228.52×(tan(45-13.091/2)*tan(45-13.091/2))-2×14.466×tan(45-13.091/2)
=228.52×(tan38.4545*tan(45-13.091/2))-2×14.466×tan(45-13.091/2)
=228.52×(tan38.4545*tan38.4545)-2×14.466×tan(45-13.091/2)
=228.52×0.886821-2×14.466×tan(45-13.091/2)
=228.52×0.886821-2×14.466×tan38.4545
=228.52×0.886821-2×14.466×0.941712
=202.656335-2×14.466×0.941712
=202.656335-28.932×0.941712
=202.656335-27.245612
=175.410723
Answer:228.52×(tan(45-13.091/2)*tan(45-13.091/2))-2×14.466×tan(45-13.091/2)=175.410723
