To calculate this expression, we first need to evaluate sin(46.9), cos(34.1), and cos(19).
sin(46.9) ≈ 0.7290cos(34.1) ≈ 0.8290cos(19) ≈ 0.9455
Now we substitute these values into the expression:
(13 0.7290 - 8 0.8290) / 0.9455
Calculating the numerator first:
(9.477 - 6.632) / 0.9455
Now subtract the numerator:
2.845 / 0.9455 ≈ 3.009
Therefore, the result of the expression is approximately 3.009.
