Answer:

[tex]\frac{\sqrt{3} }{2}[/tex]

Step-by-step explanation:

Given

sin(- 240°)

To obtain the positive angle measure add 360°, equivalent to one full revolution about the origin, then

ain(- 240°)

= sin(- 240 + 360)°

= sin120°

= sin( 180 - 120)°

= sin60°

= [tex]\frac{\sqrt{3} }{2}[/tex]
