Answer:
Below the explanation and result.
Explanation:
1) divide in possible cases
sin(x+30)=1/2
2) isolate "x + 30" and simplify
sin(x+30)=1/2
sin (π-(x+30))=1/2
3) calculate and isolate π-x-30
x+30= arcsin (-1/2)
sin (π-x-30)=-1/2
4)add period and calculate
x+30= -(π/6)
π-x-30=arcsin(-1/2)
5) resolve the equation and add the period
x+30= -π/6 +2kπ, k∈Z
π - x - 30= -π/6
6) resolve the equation
x= -π/6 - 30 + 2kπ, k∈Z
π-x-30=π/6+2kπ,k∈Z
7) like -2kπ=2kπ, so k∈Z
x=-π/6-30+2kπ,k∈Z
x=7π/6-30-2kπ,k∈Z
8) Find the union
x=-π/6-30+2kπ,k∈Z
x=7π/6-30+2kπ,k∈Z
9) RESULT:
x=-30+7π/6+2kπ,k∈Z
x=-30+11π/6+2kπ,k∈Z

<u>Translated from Spanish language:</u>"An X company dedicated to the manufacture of glass uses borax, limestone, sand, dolomite, sodium carbonate, boric acid, feldspar and sodium sulfate. In this process, minor ingredients are added that are responsible for providing some specific function as color. The materials are taken to the melting furnace comprising the progressive increase in temperature to a maximum of 1600 ° C, followed by cooling. An analysis of the pollutant emissions of this company to the atmosphere should be performed considering that there is a monitoring station which indicates the concentrations of: 26 mg / N.m.CO, 25 mg / N.m³ SO₂, 40 mg / N.m³ NO₂, 14 mg / N.m³ O₃, 67 µg / m³ PM10. It is known that the output flow of the chimney gases is 60,000 N.m³/ h and the output speed of said gases is 30 m / s. The chimney gas leaves 400 K.
• Determine the total emission concentrations in kg / year measured at normal conditions. (1 a.t.m, 25 ° C)
• Determine the diameter of the furnace chimney pipe.
• Center your analysis on: Perform an analysis of company X and its environmental impact."
