Work: Calculate the value of equation (8.5-tan30)*sin(45-12.3/2)/sin(45+12.3/2+30)+1/cos30+1.5 .
Question type: Mathematical calculation
Solution:
(8.5-tan30)*sin(45-12.3/2)/sin(45+12.3/2+30)+1/cos30+1.5
=14.905331*sin(45-12.3/2)/sin(45+12.3/2+30)+1/cos30+1.5
=14.905331*sin38.85/sin(45+12.3/2+30)+1/cos30+1.5
=14.905331*sin38.85/sin81.15+1/cos30+1.5
=14.905331*0.913126/sin81.15+1/cos30+1.5
=14.905331*0.913126/-0.506749+1/cos30+1.5
=14.905331*0.913126/-0.506749+1/0.154251+1.5
=13.610445/(-0.506749)+1/0.154251+1.5
=(-26.858356)+1/0.154251+1.5
=-26.858356+6.48294+1.5
=-20.375416+1.5
=-18.875416
Answer:(8.5-tan30)*sin(45-12.3/2)/sin(45+12.3/2+30)+1/cos30+1.5=-18.875416
