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×(tan37.4*tan(45-15.2/2))-2×13.24×tan(45-15.2/2)
=348.13×(tan37.4*tan37.4)-2×13.24×tan(45-15.2/2)
=348.13×0.095088-2×13.24×tan(45-15.2/2)
=348.13×0.095088-2×13.24×tan37.4
=348.13×0.095088-2×13.24×-0.308363
=33.102985-2×13.24×(-0.308363)
=33.102985-26.48×(-0.308363)
=33.102985-(-8.165452)
=41.268437
Answer:348.13×(tan(45-15.2/2)*tan(45-15.2/2))-2×13.24×tan(45-15.2/2)=41.268437
