sin(2x)cos(7x) - cos(2x)sin(7x) = 0.1

Answer:x≈-0.0200335+2kπ/5x≈-0.648352+2kπ/5Step-by-step explanation:sin(-5x)=0.1-sin(5x)=0.1sin(5x)=-0.1sin(5x)=1/105x=arcsin(- 1/10)5x=π-arcsin(- 1/10)5x=π-arcsin(- 1/10)5x=π-arcsin(- 1/10)+2kπ5x=π-arcsin(- 1/10)+2kπx=arcsin (1/10)/5 + 2kπ/5x=arcsin (1/10)/5 + 2kπ/5x≈-0.0200335+2kπ/5x≈-0.648352+2kπ/5
