To calculate this expression, we need to use the trigonometric identities:
sin(A) / sin(B) = (2 cos((A-B)/2) sin((A+B)/2))cos(A) cos(B) = 0.5 (cos(A-B) + cos(A+B))
Given the values sin(560), sin(400), cos(800), and sin(770), we can plug them into the formulas above to simplify the expression:
sin(560) / sin(400) cos(800) sin(770)= (2 cos((560-400)/2) sin((560+400)/2)) / (2 cos((800-770)/2) sin((800+770)/2)) cos(800) sin(770)= (2 cos(80) sin(480)) / (2 cos(15) sin(835)) cos(800) sin(770)
From here, we can simplify further and calculate the final result.
