Question Number 154786 by Jamshidbek last updated on 21/Sep/21
((sin(x+60°))/(sin60°))+((sin(x+60°)∙sin30°)/(sin(2x+30°)∙sin60°))=((sinx)/(sin60°))+1  x∈(0;60°)  x=?
$$\frac{\mathrm{sin}\left(\mathrm{x}+\mathrm{60}°\right)}{\mathrm{sin60}°}+\frac{\mathrm{sin}\left(\mathrm{x}+\mathrm{60}°\right)\centerdot\mathrm{sin30}°}{\mathrm{sin}\left(\mathrm{2x}+\mathrm{30}°\right)\centerdot\mathrm{sin60}°}=\frac{\mathrm{sinx}}{\mathrm{sin60}°}+\mathrm{1} \\ $$$$\mathrm{x}\in\left(\mathrm{0};\mathrm{60}°\right)\:\:\mathrm{x}=? \\ $$
