    Yes diksha, what's wrong?

    Sin (90+x)=cos x, So sin(90+30)=cos 30, So sin 120=√3/2

    From the trigonometric formulas,

    As we know that, sin (90 + x) = cos  x

    Then as peer the given,

    Sin ( 90 + 30) = cos 30

    {tex}cos 30 = \frac{\sqrt3}{2}{/tex}
    Therefore, the value of  sin 120 degree is {tex}\frac{\sqrt3}{2}{/tex}.

    1Thank You

    Maybe add sin 90 + sin 30.

    1Thank You
