Work: Calculate the value of equation 2.5*cos53.72*cos34.07+2.5*cos34.07*sin53.72 .
Question type: Mathematical calculation
Solution:
2.5*cos53.72*cos34.07+2.5*cos34.07*sin53.72
=2.5*-0.951437*cos34.07+2.5*cos34.07*sin53.72
=2.5*-0.951437*-0.883498+2.5*cos34.07*sin53.72
=2.5*-0.951437*-0.883498+2.5*-0.883498*sin53.72
=2.5*-0.951437*-0.883498+2.5*-0.883498*-0.307843
=-2.378592*(-0.883498)+2.5*(-0.883498)*(-0.307843)
=2.101481+2.5*(-0.883498)*(-0.307843)
=2.101481+(-2.208745)*(-0.307843)
=2.101481+0.679947
=2.781428
Answer:2.5*cos53.72*cos34.07+2.5*cos34.07*sin53.72=2.781428
