Work: Calculate the value of equation 348.13×(tan(45+15.2/2)*tan(45+15.2/2))+2×13.24×tan(45+15.2/2) .
Question type: Mathematical calculation
Solution:
348.13×(tan(45+15.2/2)*tan(45+15.2/2))+2×13.24×tan(45+15.2/2)
=348.13×(tan52.6*tan(45+15.2/2))+2×13.24×tan(45+15.2/2)
=348.13×(tan52.6*tan52.6)+2×13.24×tan(45+15.2/2)
=348.13×1.090608+2×13.24×tan(45+15.2/2)
=348.13×1.090608+2×13.24×tan52.6
=348.13×1.090608+2×13.24×-1.044322
=379.673363+2×13.24×(-1.044322)
=379.673363+26.48×(-1.044322)
=379.673363+(-27.653647)
=352.019716
Answer:348.13×(tan(45+15.2/2)*tan(45+15.2/2))+2×13.24×tan(45+15.2/2)=352.019716
