Work: Calculate the value of equation 27*((1-(tan28/tan80))*(1.5*5+(1/2)*((5^2)/tan80)-(0.5*1.5^2*tan28))) .
Question type: Mathematical calculation
Solution:
27*((1-(tan28/tan80))*(1.5*5+(1/2)*((5^2)/tan80)-(0.5*1.5^2*tan28)))
=27*((1-(-0.031257))*(1.5*5+(1/2)*((5^2)/tan80)-(0.5*1.5^2*tan28)))
=27*(1.031257*(1.5*5+(1/2)*((5^2)/tan80)-(0.5*1.5^2*tan28)))
=27*(1.031257*(1.5*5+0.5*((5^2)/tan80)-(0.5*1.5^2*tan28)))
=27*(1.031257*(1.5*5+0.5*(25/tan80)-(0.5*1.5^2*tan28)))
=27*(1.031257*(1.5*5+0.5*2.77665-(0.5*1.5^2*tan28)))
=27*(1.031257*(1.5*5+0.5*2.77665-(-0.316609)))
=27*(1.031257*9.204934)
=27*9.492653
=256.301631
Answer:27*((1-(tan28/tan80))*(1.5*5+(1/2)*((5^2)/tan80)-(0.5*1.5^2*tan28)))=256.301631
