To calculate this expression, first convert the angles from degrees to radians:
311sin(131°) = 311sin(131(π/180)) ≈ 263.961cos(19°) = cos(19(π/180)) ≈ 0.945
Now plug these values back into the expression:
311sin(131) + cos(19)cos(19)= 311263.961 + 0.9450.945= 82266.171 + 0.8925≈ 82267.063
Therefore, the value of the expression is approximately 82267.063.
