Work: Calculate the value of equation (8.5-tan30)*sin(45-21.06/2)/sin(45+21.06/2+30)+1/cos30+1.5 .
Question type: Mathematical calculation
Solution:
(8.5-tan30)*sin(45-21.06/2)/sin(45+21.06/2+30)+1/cos30+1.5
=14.905331*sin(45-21.06/2)/sin(45+21.06/2+30)+1/cos30+1.5
=14.905331*sin34.47/sin(45+21.06/2+30)+1/cos30+1.5
=14.905331*sin34.47/sin85.53+1/cos30+1.5
=14.905331*0.087408/sin85.53+1/cos30+1.5
=14.905331*0.087408/-0.649555+1/cos30+1.5
=14.905331*0.087408/-0.649555+1/0.154251+1.5
=1.302845/(-0.649555)+1/0.154251+1.5
=(-2.00575)+1/0.154251+1.5
=-2.00575+6.48294+1.5
=4.47719+1.5
=5.97719
Answer:(8.5-tan30)*sin(45-21.06/2)/sin(45+21.06/2+30)+1/cos30+1.5=5.97719
