Question

Find the value of sin120°

Answer 1

Step-by-step explanation:

The value of sin 120° is √3/2.

Answer 2

Answer:

The value of sin 120° is √3/2.

Step-by-step explanation:

We have to find the value of sin120°.

We know that,

sin(180°- x) = sin x ---------------- (1)

Also, 180° – 60° = 120°

So, sin 120° can be written as sin(180°- 60°)

⇒ sin 120° = sin(180°- 60°) --------------- (2)

(2)Therefore, sin 120° = sin 60° [From (1) and (2)]

From the trigonometric table, we have the value of sin 60° that is equal to √3/2.

Thus, sin120°

= √3/2Hence, the value of sin 120° is equal to √3/2.
