Work: Calculate the value of equation 25*(1+0.7*cos(54.3)-0.3*cos(108.6)) .
Question type: Mathematical calculation
Solution:
25*(1+0.7*cos(54.3)-0.3*cos(108.6))
=25*(1+0.7*cos54.3-0.3*cos(108.6))
=25*(1+0.7*cos54.3-0.3*cos108.6)
=25*0.625025
=15.625625
Answer:25*(1+0.7*cos(54.3)-0.3*cos(108.6))=15.625625
