    Answer:

    Step-by-step explanation:

    According to the ratios table, if

    sin theta = 1/2

    Then theta = 30°

    Cos theta = cos 30° =root 3 /2

    Step-by-step explanation:

     \because \sin \theta =  \frac{1}{2}  \\   \therefore \sin \theta =  \sin 30\degree \\   \\ \huge \red{ \boxed{ \therefore  \theta = 30\degree }} \\  \\  \cos \theta =  \cos 30\degree  \\  \huge \purple{ \boxed{\therefore \cos \theta =   \frac{ \sqrt{3} }{2} }} \\
