. Find the value of sin 120°

Best Answer

Explanation:-

The unit circle, the value of sin120 degrees can be determined using other angles such as 60 degrees and 180 degrees which are derived from trigonometry tables.

As,

180°- 60° = 120°

The trigonometric identity sin(180°- a) = sin a

Now,

sin (180°- 120°) = sino 120 degrees

Hence, sine 120 degrees = sin 60 degree

Hence, the value of sin 120 degrees is .

Final Answer:

 the value of sin 120 degrees is
