Question

find value of sinœ+sin(120°+œ)​

Answer 1

Answer:

√3/2

Step-by-step explanation:

By using the value of cosine function relations, we can easily find the value of sin 120 degrees.

Using the trigonometry formula, sin (90 + a) = cos a, we can find the sin 120 value.

As given, sin (90° +30°) = cos 30°

It means that sin 120° = cos 30°

We know that the value of cos 30 degrees is √3/2.

Therefore, sin 120° = √3/2.
